If we want to turn this into a game of code golf, then a few characters can be shaved: Thanks to precedence rules, using '|' in place of ',' means you can drop a pair of brackets. To save 2 characters, "empty" can be replaced with "not". Also, It is also possible to trim the whitespace between '*' and 'except', but that is really getting nasty.
