Fix element values to have a proper function type when they take an argument.  Now this:

data MaybeInt {
  None,
  Some int
}
var c = MaybeInt::Some 4;
var d = MaybeInt::Some;

-ast-dump's into:

(vardecl 'c' type='MaybeInt'
 (apply_expr type='MaybeInt'
   (declref_expr type='int -> MaybeInt' decl=Some)
   (integer_literal type='__builtin_int32_type' value=4)))
(vardecl 'd' type='int -> MaybeInt'
 (declref_expr type='int -> MaybeInt' decl=Some))
