[Haskell-beginners] can this be made shorter?

No, it would be desugared to:
dropWhile ((a,b) => a == '.' || b == '/')

scala> "abc".dropWhile(_ == '.' || _ == '/')
<console>:8: error: wrong number of parameters; expected = 1
               "abc".dropWhile(_ == '.' || _ == '/')

You would have to do the same thing as in Haskell to make it work:

scala> "abc".dropWhile(a => a == '.' || a == '/')
res20: String = abc
