The regex sublanguages and engines in Ruby and Python are knockoffs of the equivalents in earlier Perls. But this thread really ought to be focused on Perl 6. In Perl 6 one can write: print "match" if something ~~ /<th

Both Perl 5 and Python 3 are built with the assumption that a "character" is what the Unicode standard generally refers to as a "character". This is a serious problem and will I suspect one day be understood to be the bi

Fwiw, the Haskell: [ x*y | x <- [2,4..8], y <- [-1,0,1] ] -- [-2,0,2,-4,0,4,-6, 0,6,-8,0,8] could be translated to the Perl 6: [2,4...8] X* [-1,0,1] # (-2 0 2 -4 0 4 -6 0 6 -8 0 8)

Because I think folk will be inclined to refer to and even hype this Craig's List hosted "event" as something akin to a launch of Perl 6 1.0. Some will be well-meaning. Some will be malicious. But it won't matter. Perl 6

It's quite possible that Larry agrees with you. I've never heard him suggest that it was a mistake to build on Perl 4 to get to Perl 5. Which implies that he considered it worth A) continuing to evolve Perl and B) building directl

The article you've linked is about unityped languages. Perl 6 is not unityped. To quote the conclusion of the article you linked: > Why should you care? Because, I argue, that a fully expressive language is one that supports the de

I rebuilt everything... and p6doc failed to build. It turns out that the glr branch got merged about 5 hours ago (about the time you started commenting). I'm posting this now, before I catch up with the irc backlog, to give you a heads

If you search back to the comment that started this subthread you'll find it began: "Try 0.1 + 0.2 == 0.3 in some other language, then try it in Perl 6." Do you agree with all of the next sentence or not? Please start with a

Hmm. I'm using my account on the Perl 6 community dev server hack.p6c.org. I used rakudobrew to rebuild rakudo last night: This is perl6 version 2015.07.1-215-ge6f3602 built on MoarVM version 2015.07-108-g7e9f29e I just ran `panda inst

Do you know if there was ever any public discussion about whether to represent decimal fractions (0.1 etc.) as an exact rational or inexact float?

by raiph 11y ago
The use of an annotative '#e' to get an exact number contrasts with Perl 6's choices for the default interpretation of number literals. The Perl 6 choice adopts scientific notation to correspond to floats: 2000000000000

by raiph 11y ago
Ah. glr is 1) a very recent in-development branch that 2) only includes the compiler so 3) panda (the module installer) isn't included and 4) it may not work even if you download and manually install a copy of it. You might want to vis
