Nick Hamann f0af1eb110 Warn when creating a module and a struct that both have the same name.
Currently it is possible to do the following:

 - define a module named `Foo` and then a unit or tuple struct also named `Foo`
 - define any struct named `Foo` and then a module named `Foo`

This commit introduces a warning for both of these cases.
