Lvalue substr() is my special friend. Did you know you can bind regular expressions and transliterations to them?

  my $x = "x" x 50;
  substr($x, 12, 34) =~ tr[x][y];

Foreach's iterator variable is an alias for an item in the list being iterated through. This works with values() and hash slices, too.

  my %x = (a=>1, b=>2, c=>3);
  $_ *= 2 foreach values %x;

I'm so, so easily amused. :)
