I converted that Perl 6 code to Perl 5 best I could and came up with
Here's a slightly more direct conversion
sub apply(&@) { ## ack, Class::Multimethods doesn't do variadic args :-/ return if @_ == 1; my($func, $head, @tail) = @_; local $_ = $head; return $func->(), apply($func, @tail); } my @squares = apply { $_ * $_ } 2 .. 5; print join(', ', @squares), $/; __output__ 4, 9, 16, 25
As the comment gives away, this isn't a direct conversion as it isn't using multimethods, so it uses an arg count hack to emulate the behaviour. Also to be an even closer conversion would require apply to tie @squares to a square generator (at least I think that's probably the closest thing you can get to binding to a lazy list in perl6 with raw perl5). So it's certainly no easy task to convert that wee but powerful snippet directly to perl5!

      Should cpanminus be part of the standard Perl release?
