I saw a bit of that when someone on P5P mentioned that perltoot (Tom's object-oriented tutorial for perl) didn't exist anymore. His argument for keeping it was simple. https://www.nntp.perl.org/group/perl.perl

It wasn't even stagnant for a full 10 years, let alone 20. Perl 5.8 was released in 2002 Perl 5.10 was released in 2007 It has had a release every year since 5.12 in 2010. The latest was 5.32 on 2020-Jun-20. (Less than a year ago.) The

The MoarVM and JVM backend supporting code was, and still are, very similar. The Parrot backend supporting code was significantly different. So much so that to properly support Rakudo on Parrot would require a rewrite of it. There are var

Actually `=` sort-of only does one thing. It asks the left argument what it wants to do with the values. my @a = 1,2,3; is almost the same as my @a; @a.VAR.STORE((1,2,3)); --- As for separate positional and associative

The Raku idea is that an operator only does one thing. That way you can tell at a glance what the operator is doing. If you want to do something else, create a new operator. (One of the design mottos was “Similar things should look similar,

You could do it the way Raku does. It's implementation defined. (Rakudo on MoarVM) The way MoarVM does it is that it does NFG, which is sort of like NFC except that it stores grapheme clusters as if they were negative codepoints. If a

cygx incorrectly thinks that the Apocalypses, Synopsys, Exegesis were the specification. There is a reason we don't try to keep them up to date [anymore]. They are historical documents that were used to discuss and understand what the

The specification is the test suite. (Which has been kept up to date.) A text specification like the one C has is bordering on useless. There are plenty of things that are “implementation defined”. I think it was C that had to resort to say

Ironically making it more modern may make things like shell scripting easier. Let's say that Perl gets a real type system, and reflection capabilities. Then I can see something like this come to exist: use v7; use GetOpt::MAI

Raku is a significantly higher level language than most languages. Which tends to lead to slowness. Really it's faster in many places than it has any right to. @a[1]; Is just shorthand for a subroutine call. postcircumfi

Somewhere I have posted code that uses Inline::Perl, Inline::Python, Inline::Ruby, and I think maybe Inline::Go to convert Base64. (Perhaps other language interfaces as well, I don't quite remember) While there were some quirks, It wor

I didn't realize that concatenating two strings was the same exact concept as adding two numbers together. You learn something new everyday. Oh, they're not? Then why are you using the same operator? ... They reused the operator b

There are many good ideas that aren't in one programming language or another. Does that actually mean they are bad ideas? No. It only means that particular language didn't copy that particular idea. There may be bad ideas that a

The problem with types in Python is that the compiler doesn't enforce the types. Perl will actually enforce the types.

The Rakudo implementation actually uses Raku regexes to parse Raku. To be fair though it is a lot easier to do that with the redesigned regexes that Raku has. Basically you can use backreferences for that if you also allow the regex to be r

Raku allows strings inside of strings. Of course it does this by way of embedded closures. "abc{ "def" }" Which allows it to be arbitrarily deep. "a{ "b{ "c{ "d{ "e{ "f"

The Python 3 changes aren't big changes. They are breaking changes however. I know they aren't big because Perl has had to deal with many of those same type of problems, only it didn't have to break old code to do it. Perl

Perl is a write once language for me. In that I write it once and 20 years later it still works even though I upgraded the compiler many times.

While Raku is generally slower than other languages, there are times when it is is faster than those same languages. There was even one report of it being faster than C/C++. (My guess is that the C/C++ code was doing a lot of stri

I fully expect that Raku will be as influential a language as Perl was before it. --- JavaScript has a `"use strict"` mode, that was copied from Perl5. PowerShell has a `$_` variable that was copied from Perl. Every language that

To be fair some of the things in HOP are just features that already exist in Raku. use v5 use Stream 'node'; sub iterator_to_stream { my $it = shift; my $v = $it->(); return unless defined $v;

That's exactly what Perl has been doing since 1987. Where do you think the idea for `"use strict"` in JavaScript came from? use v5.8; use strict; use warnings;
