Re: Perl 6 strings, interpolation and templates?

[ikegami]

You can already do that in Perl 5:

say "Hello @{[ join(', ', @names) ]} how are you?";

There's no security issue because it's not say that causes the interpolation, it's the string literal. And it's no more possible for someone to provide a string literal as they could provide a for loop.

use strict;
use warnings;

use 5.010;

my @names = qw( ikegami );

say "Hello @{[ join(', ', @names) ]} how are you?";

my $user_input = q{Hello @{[ join(', ', @names) ]} how are you?};
say $user_input;

Hello ikegami how are you?
Hello @{[ join(', ', @names) ]} how are you?

Ah yes, 5.10... version limitations at work means that I've not read the perldoc for it yet. :-(

Thanks. Sorry for stupid q.

[almut]

It's just the say that's 5.10 specific here... the interpolation mechanism already worked like this before...

(This is just array interpolation with an anonymous array — in between the [...] can go arbitrary code.)

This is embarrassing, how could I have missed that?! (Camel book etc are@work. Seems to have left my brain there too.)
