Agreed on both counts.

Actually if you don't mind I shan't bother trying that change, because
it /would/ slow a lot of things down - see "$&" in "man perlvar":
	The use of this variable anywhere in a program imposes a considerable
performance penalty on all regular expression matches.

My current favourite patch for the problem is here:

Feedback appreciated!
