new MyClass.MyClass(), I suppose. Despite import is public, 
module symbol has higher priority in name resolution.

Nope. I changed module name to myClass_mod, now got this:

  Error: class myClass_mod.myClass() is used as a type

class myClass () {

should be

class myClass {
    this() {

    }

BTW I just sent a pull request that makes rdmd faster for large projects 
by reducing the number of stat calls:

Yeah... Those empty parentheses were making myClass a class template, 
not a class. Apparently the syntax (or the compiler) allows template 
definitions without template parameters, which can still be instantiated:

class myClass () {
   this() {

   }
}

int main() {
     myClass!() my_instance = new myClass!();
   return 0;
}

You need to put myClass_mod.d (or what ever the file name is) on 
the command line. You could also use rdmd, which will find all 
the imported files automatically.

module myClass (myclass.d);

     class myClass() {
         this() { ... }
     }

and main app (main.d):

     import myclass;

     void main() {
         myClass my_instance = new myClass();
     }

then compile with:

     $ dmd main.d myclass.d
or:
     $ dmd main myclass
or:
     $ rdmd main


ps. Module names should be lowercase (see docs), and you can 
safely use 'void' for main()

Whoops, forgot to remove the '()' after 'myClass'. As others have 
pointed out, that will make 'myClass' a template-class.
