[swift-evolution] [Discussion] Namespaces

[Tyler Cloutier]

This seems like a problem that would be better solved by adopting the Python philosophy that you must provide the full namespace for types, either upon import or explicitly in the code. It also makes searching things in the code easier as it’s clear exactly which namespace each type belongs to.

I don’t see any other motivation for why would you want to force a developer to use the submodule name. If there are no conflicts, why force them to use it?

"Node" may be a perfectly fine name for these. That said, these are sometimes tied to specific types in which case nesting them may make more sense, which I believe is already being addressed (currently we can't nest generic types)? It's certainly not as simple as it can appear!
