I read somewhere (probably in the CookBook) that it's faster to execute this :
$string=~s/^\s+//; $string=~s/\s+$//;
Than the one-liner :

$string =~ s/^\s+|\s+$//g;

Edited by davido: Removed useless use of /g modifier from the two-line (faster) example.

    Note that the /g in the two line example are pointless. There's no need to repeatedly remove all whitespace at the front or end.
