Re: Favorite Perl 6 feature?

[mirod]

My favourites:

• the entire new regexp system, which will allow us to write grammars directly in the language,
• the type system, which will most likely allow us to reduce the amount of memory used by Perl when needed,
• wrappers around subroutines (along with temporization), will make testing much easier, it will be possible to write stubs for existing functions,
• "cute" feature I like the most: the "pipe operator" (==> and <==),
• and of course Parrot is great idea, I want to be able to use the best ruby/python/brainfuck libraries (OK, maybe not brainfuck ;--)

That's pretty much like me. In the regexp I like that 'closure' property - that you can call code from regexp and the other way. And as for cute operators I like the vector operators. For the last point about Parrot - well Perl libraries are I think the bigest so I believe it will be much more the other way around - ruby/python/brainfuck programmers using Perl libraries.

[diotalevi]

Regexps are already closures via the ??{ construct. You just can't jump back into regexp because the engine isn't re-entrant (though I hear it works a bit - I seem to fall over all the nasty bits). What I'm really pining for are:

• Grammars for binary data (P::RD chokes)
• Being able to locally redefine the language
• Getting full access to the VM and in a meaningful way since perl5's VM is so clunky to work with
• Junctions!
• Lazy pipelining
• Co-routines

And I want these not because they're cool but because at various points I could have made my own code simpler, more efficient or had some otherwise significant improvement.

Grammars for binary data (P::RD chokes)

I guess preprocessing the input into strings of 1s and 0s isn't (?x: fast | efficient | good ) enough? (Should get around the choke no?)

;-)
