#perl 6

[floofshy]

Perl 6 is so into “there is more than one way to do it“, that with the new release Perl 6 now has two names: Perl 6 and Raku. You can use Raku if you find Perl 6 to be too of a confusing name.

confession time: i usually don’t actually choose the questions when i send someone askmeme questions

i just open up my perl 6 interpreter and do something like this

> (1..50).pick(5).sort; (14 25 27 35 37)

perl 6 is nice, you guys

From this Perl 6 presentation:

Whatever Code

Each WhateverStar represents the next positional argument. You can't use WhateverStar to refer to the same argument more than once:

say ( * + * + * )(2, 3, 4); # OUTPUT: # 9

(No, this is not an April Fool’s joke.)

My first question (of many, many questions): how do I multiply!? And if anybody says ( * * * * * )(2, 3, 4) will “just do what you’d expect”, I’ll... stare at them incredulously. And continue to use Python.

fun fact, perl six has a way to solve that problem i just posted about!

specifically it has a but operator which works like this:

my $x = 0 but True; if $x { // this code block will be run } if ($x + 0) { // this block won't be }

so the "run system command" subs return a 0 but True on command success, or a 1 but False on failure!

pretty neat

And in the backslashed form, [the reduction metaoperator] needs something with a vertical feel on the left representing the "left margin," or we lose much of the triangular feeling, so square brackets work nicely together with backslash that way. It all adds up to an almost overwhelming feeling of necessity -- which is why the language designer must also guard against adding up too many apples and then comparing them to orangutans.

TimToady a.k.a. Larry Wall, or was it vice versa?

Yes, we really will [have Perl 6.] We have a complete parser now, written in Perl 6, that parses itself, and can spit out an AST. All that remains is to come up with a VM with sufficent support for lazy functional OO semantics, and write an emitter for it. Simple!
