           Summary: bad error message caused by UFCS attempt on the
                    identifier matching to an import

module a;

class Foo
    private int x;

module b;

import a;

void test(Foo foo)

then in the same directory as the two files

$ dmd b.d


 Error: function expected before `()`, not `module a` of type `void`
The real problem here is that `Foo` does not contain any member named a. The bad message leads to think that the compiler tries a function `foo` on the import `a`, i.e by UFCS but the only existing `foo` is a class. Also if you look at the command line you can note that "a.d" is not specified. I don't know why dmd automatically detects the file. If this is part of this strange issue then what is expected is
 module `a` is in file 'a.d' which cannot be read
