Granted, I'm more of a hobbiest than a dev, but I think this is part of the problem that virtualenvs are supposed to help solve. One project (virtualenv) can have numpy==3.2, and another can have numpy==3.1. Maybe I'm naive, but it seems like having a one project with multiple versions of numpy being imported/called at various times would be asking for trouble.

The thing you can’t do is solve for this situation.

    A depends on B, C
    B depends on D==1.24
    C depends on D==2.02

There should in an super ideal world be no problem with this. You would just have a “linker” that inserts itself in the module loader that presents different module objects when deps ask for “D” but it hasn’t happened yet.
