So, both these from the docs work fine:
[% first_three = list.slice(0,2) %]
[% last_three = list.slice(-3, -1) %]
But this doesn't:
[% the_rest = list.slice(3, -1) %]
Might be nice if it did though it's not the real perl behavior.
Not saying it's needed or even a good idea, just throwing it out
there b/c I like the idiom.
So, the "$to" line (Stash.pm):
'slice' => sub {
my ($list, $from, $to) = @_;
$from ||= 0;
$to = $#$list unless defined $to;
return [ @$list[$from..$to] ];
},
becomes...? maybe? (untested)
$to = @$list + $to if ( $to < 0 and $from > 0 );
$to = $#$list unless defined $to;
