in reply to Perl Optimization

Just some slight, stupid optimizations to save the slightest bit of space.

  • substr before regex (if possible). transliteration before regex. Use regex as last resort.
  • use single quotes if no interpolation is needed (REALLY minor optimization).
  •  $foo ? $bar; is faster than $bar if $foo; which is faster than if($foo){$bar}.
  • require is always faster than use.
  • use Memoize if that slow function that is called a couple times needs speeding up.

Tiptoeing up to a Perl hacker.
