r.e. glob imports, the ‘inherit use’ idea,…
Imagine if on not finding a symbol , Rust did the following:-
 breadth-first search for it in submodules of the current module  step back to the parent, and repeat the search … (until you reach the root)
I’m guessing the objection would be that subsequent changes to a source base could break such ad-hoc symbol references , so this would leave projects in a brittle form if they relied on this
What if you enhanced this with a ‘fuzzy path match’ … e.g.
vec::Vec would both locate
std::vec::Vec in preference to a
Vec in any other location - and made it a warning when a completely unqualified assumed path was being used.
Could this be better than the temptation toward indiscriminate glob imports - another way of reducing the micromanagement of modules & symbols, and sharing a lot of context between related files automatically
