not to imply I think wildcards are a good idea in python, but pyls (the
language server protocol implemention for python) makes it nearly trivial
to navigate to the place where each symbol is defined, just by using the
go-to-definition command. it can be used with vim and many other text
editors/IDEs, such as VSCode (what I use, mostly because it has the best
Rust support out of all non-vim editors).

I quite like how rust handles wildcard imports: all explicitly named
imports take priority over wildcards and if there is a name that comes from
multiple wildcard imports, then it errors with an ambiguity error.
