Actually migrating from Perl5 to Raku may be less painful than migrating from Python2 to Python3 for some codebases. That is because you can easily use Perl5 modules in Raku. use v6; use Scalar::Util:from<Perl5> <looks_l

The way Perl dealt with this was to have you declare when you are using UTF8. # declare that the code itself is written in utf8 use utf8; my $ā = 'ā'; If you need unicode strings to work, you turn on the unicode

Raku and Rakudo are different words. “Raku” is the anglicized form of “楽”, which means “easy”. (It is also a form of pottery.) “Rakuda do” is supposed to be “way of the camel”. “Rakudo” is “Rakuda do” but shortened/portmanteau. “Rakudo

That is not actually the same thing. PHP 6 was thrown away never to be seen from again, because it was seen as bad. Perl 6 was renamed because both Perl 5 and Perl 6 are significantly different active languages. If Perl went to 7 it could i

I would prefer if they created a year alias to the version. So both of these lines would be equivalent. use v5.32; use Perl v2020;

You really wouldn't really need to in Raku. Mainly because you can add things to the existing parser instead. (See postfix and infix below.) role Physics::Datum { has Real $.value is required; } role Physics::Distan

I've heard about a merger between two companies. One use Java, the other used Perl. At some point both teams were told that they had to add a particular feature. The Perl team was done well before the Java team. This was a story from o

You do realize that there are more Perl programmers and more Perl code written today then there was back in '99 when Python 1.5.2 was released. Sure the percentage has gone down, but the count has gone up.

Raku is not fast for mostly different reasons. Right now one of the slow parts is the regex/grammar feature. So code that uses that feature is a bit slower than it needs to be. The compiler uses the regex/grammar feature, so your

I didn't mean in Perl. If you actually read what I wrote, you'll note that everything I said makes it a difficult to impossible in Perl. I meant adding the feature to Rust, which doesn't have the same difficulties.

It was a problem in Perl, it isn't in Raku. Part of the problem is that Perl doesn't have as strong of a type system. (Is is an int or a string, or is is both? The runtime certainly doesn't know.) It was also symmetric in 5.1

In Raku those things are also separate. 1. Polymorphism class Example { method be-nice () { 'be nice' } } class Bill-and-Ted is Example { method be-nice () { 'be excellent to e

Multi-threading and Junctions auto-threading are NOT the same thing. Calling it auto-threading has lead many people to the wrong conclusion. (It is possible that auto-threading may be done multi-threaded in the future, but it doesn't d

Roles take the place of all of these: - Java interfaces - abstract classes - C++ templates - Python mixins - Smalltalk traits So are you telling me that you haven't used any of those? --- Roles combine all of those features very simply

Perl 5.000 came out in 1994, the same year as Java. Perl didn't even have objects before that. So no it wasn't from experience with Perl.

What functionality does Python have that Perl doesn't? I'm legitimately asking because I'm pretty sure there is almost no functionality in Python that isn't in Perl. In fact of the features I've read about that chan

I have yet to find out about a Python 3 change that couldn't have been handled in a backward compatible way. I know this because every change I've heard about is reminiscent of a Perl5 change where backwards compatibility was not

Everything that I've heard that was changed from Python 2 to 3 are reminiscent of things that Perl5 handled while maintaining backwards compatibility. I mean Perl5 is still mostly backwards compatible back to the original version relea

Note that: while (<>) { ($h{$_}++ == 1) && push (@outputarray, $_); }; Would be written as the following in Raku: my @output-array = lines.unique;

I want to know who taught you math. Because 2015 - 2000 does not equal 20. The project started in 2000. --- It would have been a much worse language if it had been released even a few months earlier. (That was before the GLR landed.) --- Al

Yeah, I don't think that anyone learning Raku that way would realize that the {} in the following is actually a lambda. for @a { .say } So this works in basically the same way: my $lambda = { .say } @a.map( $lambda

What's surprising is that there is evidence that they originally evolved to deal with the snows of the arctic. So those feet that are great on sand were made for walking on snow covered ground. Likewise food is scarce in both the arcti

I think it would be a better idea to make the minor number be the major number. So skip to 32.

Microsoft had to skip 9 because programmers are lazy. A lot of programs refused to work if there was a `9` in the version name. That was of course because those programs needed something newer than Windows 95 or Windows 98. So they just did

This has the benefit of showing that Perl gets a new version released every year. I have previously stated that I would like it to be an alias of sorts. use v5.30; use v2019; Basically have both of those lines do the same thin

I have a different perspective. When I have a bit of Raku code that is too slow I complain (send a bug report) and then someone else figures out why the JIT isn't doing a better job and fixes it. Then bingo-bango it ends up even faster

Especially since you can use the Inline::Python module.
