GB> Fine with me.
might as well use a different modifier like the proposed /t. this is not
like /ee which does the eval twice. you can't do 'global' twice.
another point might be to make /g and /t in scalar context mutually exclusive
(fatal error) since /g means remember where we matched for the next time
and /t means count all the matches.
