Well, you could use:
null . dropWhile (`elem` "./")
=)

hi,
i want to know if a string contains only "." and "/" characters.
i do something like that:
null . dropWhile (\c -> c == '.' || c == '/')
now it's a shame, because if I wanted only to check for "." then I would have:
null . dropWhile (=='.')
afaik in scala you can say:
null . dropWhile (_ == '.' || _ == '/')
which is a bit more compact than the haskell...
I was thinking to use "and" but I'm not sure it would end up being readable...
Any idea? Or I am trying too hard to make it compact?
Emmanuel
