[Haskell-beginners] can this be made shorter?

[Emmanuel Touzery]

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
