Please ...<P><P>
$1 is a global variable which should only be carefully used in local context.<P><P>
But your match within the sub changes this global variable and your alias in $_[0] reflects this.<P><P>
And after leaving the sub the implicit localization restores the old value of $1...<P><P>
Better stop messing with perl internals or just pass a copy of $1 or follow [choroba]s suggestion.<P><P>
