class name scoping

What happens in Smalltalk if multiple categories contain a class with the same name? Is that allowed? If so, how do you specify which one you want?

Not allowed. Squeak has no namespaces. Categories have no "semantic"
meaning, it is only for organisation.

That's why almost all Squeak libraries use a prefix for class names:

As Lukas wrote we tend to use prefixes.

This is a long standing discussion/debate on merits of namespace
solutions etc. I have my proposal with code to back it up here:
