For people who don't know the syntax, "a/**/b" is equivalent to "a/*/b or a/*/*/b or a/*/*/*/b or ..." (for as many levels as needed).
Or a/b.
Hmm, from my experiments, bash doesn't show a/b as matching the pattern a/**/b ...
One obvious downside is that if used carelessly, it can make globbing pretty slow. So I'd propose that it be added as an optional extension enabled using a flag argument (glob(pat, allow_recursive=True)) which is false by default. That would also mean that backward compatibility should not be an issue.
Indeed. That's why I added the "recursive" parameter and disable this by default.
Although I can see Vinay's point, that ** is not useful syntax currently, so there's no compatibility problem. Careless use resulting in long glob times is more of a user issue. Having said that, this debate is *precisely* why I suggested making it a parameter in the first place, so people can choose for themselves. So I guess I agree with your decision :-) Paul.
