Indeed you don't, however, the yhc compiler only cares about being able 
to separate the module name so the change is sufficient for its purposes.

To give a truely unique and unambiguous name something like

Foo.Bar;Prelude.Eq;Foo.Bar.Baz;==

would be necessary. This would also be a possible encoding if people 
thought it was preferable.
