Still, we should consider functions with names like Float. Currently they
are not highlighted correctly - Something(test) is highlighted as a
constant, when obviously it's not. I guess classes, constants and functions
like this could be font-locked after the first character that's not part of
the identifier name appears, to avoid the changing of the face after the
initial character.
