Ouch... That explains everything. I guess I'll have to go over the 20 files
and look if it's just a sequential function or intended to be an instance...

Removing instances() would IMO make MyHDL quite unusable... It's already
tedious to explicitely return the implicitely instantiated modules. If I
have to care manually about the correct instantiation of my modules, I can
just use raw threads and shared variables ;-)
