Re: I need some wisdom. How do I pack an array to a set length.

The "x" operator works with ~~arrays~~ lists as well:

@b=qw(h o r s e );
$x=4;

push @a,$x,((@b) x $x);
print join(",",@a);

Edit: /nods to Tux; yeah, sometimes I forget my terminology.

Though you're example is perfect, your wording is not. `x` works also on lists, not on arrays: `$ perl -E'@x=("a".."c");@y=@x x 3;say@y' 333 $ perl -E'@x=("a".."c");@y=(@x)x 3;say@y' abcabcabc $` [download] That is why the extra parens are needed, otherwise the array would be evaluated in scalar context by `x` and hence returns its length.
