Sorry for bumping this given that this was opened in 2016. We would really like to see extended globbing and I wanted to ask if there's any way we could help here? I have to say that I don't really feel comfortable with AST and lexers but with some pointers I might be able to help.

Hey @aeneasr, will try to take a look on it next weekend.
