re ...
As I understand it the generated code is not exported from the
translation unit so there are no collisions at link time. We could do
the same if we could force the generated type class instance to not be
exported from the module.
I have encountered several occasions when I wished control over what
instances get imported or exported from a module.
I have wondered and perhaps someone can explain: what are the issues in
explicit control of instance export and import? (apart from defining an
appropriate syntax)
