Here's a fun little hole: Write a function that runs under use strict; which returns a list of the files in the current directory that contain a certain pattern. The pattern to match is passed to the function. Here's an example usage: 
use strict;

sub filegrep {
  ...
}

my @files = filegrep('Match this!');

My best is 56: 

sub filegrep {

#         1         2         3         4         5
#12345678901234567890123456789012345678901234567890123456
 my@k;for(<*>){open F,$_;push@k,$_ if grep/$_[0]/,<F>};@k
}
