There's a rejected RCR (from me :-) that proposed a second argument to
Dir.glob, that second argument being a filter for Kernel#test.  So then
you could do:

   Dir[glob, 'd']

to get directories.  As I said, it's been rejected as an RCR, but
anyone who wants to see/use the implementation can find it at:
