Re: List::MoreUtils before, after and ... between?

No good for one-liners, but this looks pretty sweet:

use 5.010;
use strict;
use List::MoreUtils qw/first_index last_index/;

sub narrow
{
    my ($from, $to) = map { $_->(@_) } @{(pop)};
    return @_[$from .. $to];
}

sub from (&$)  { [ @_[0..1] ] }
sub to (&)     { $_[0] }

my @list = qw/eval DBIC::1 DBIC::2 My::1 My::2 My::3 Dancer::1 Dancer:
+:2 Dancer::3 Dancer::4/;

say foreach
    narrow @list,
    from   {   1  + last_index  { /^DBIC/ }   @_ }
    to     { (-1) + first_index { /^Dancer/ } @_ };

Obviously you'd want to factor narrow, from and to out into a separate module rather than defining them inline.

And given that from and to are quite generic names, perhaps something like start_at and finish_at might be better in practice.
