Er... but in a scalar context, m//g DOES only match once! If you want
more, repeat the match. Or use it in a list context, then it will try to
match them all.

	$_ = "abaabbbababbbabbaaa";
	while(/(b+)/g) {
	    print "Got a '$1'\n";
	}
-->
	Got a 'b'
	Got a 'bbb'
	Got a 'b'
	Got a 'bbb'
	Got a 'bb'

Let's try again:

	$_ = "abaabbbababbbabbaaa";
	print scalar(() = /b+/g);
-->
	5

Is that what you're after?
