Assume I have a string $s with length greater than $ml. I would like to create an array containing the successive pieces of $s, each piece with length $ml (the last piece probably shorter). For example: 

$s='abcdefg';
$ml=3;
@result=('abc','def','g');

Restrictions: Must run under perl 5.8 without additional modules (CPAN) installed.

The first thing which came to my mind, was to use split to turn the string into an array of characters, 

@sc=split(//,$s);

[download]
and then, using a loop, use Arrayslices to extract the individual parts of the string, i.e. inside a loop something like: 
push @result,join('',@sc[$i*$ml .. $i*($ml+1)-1]);

[download]
But even if we ignore for a moment the problem that the last slice would be out-of-bounds (which is trivial to solve), this solution is terribly ugly. Is there a better way to do it? Maybe with a regexp containing .{1,$ml}, but I don't see how to use this to build up my resulting array (I would need kind of a "generator"). Any ideas?
