A feature I'd like to see added: a few user definable character classes.
Call them \X, \Y, \Z.  These could be used in regexp's without the
additional overhead or confusion of using $vars.

Example: I define \X to be [\w-$_] -- with whatever syntax.

Now I can have complex substitutions

		s/<([.\X]+!)+(\X+\.[.\X]+!)/<$2/;
	
with good performance.  It seems straightforward to modify regcomp.c
to use \X thru \Z if defined.
