Ideally we would have flexible import syntax that allows for control over *how* names are imported into a lexical context (including the ability to import names within a very specific scope if desired).

All submodules are part of the same target as the module that contains them.

Cross decencies? I don’t understand.

But it is a practical and effective one. Introducing a new construct like namespaces must carry significant advantages over what is already possible.

"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!
