due to the lack of a marker that denotes where the module ends and the attribute starts, unrelated import errors can break the try&error chain at unexpected places and the code can pass on to the recursive getattr chain, giving a completely different error instead of the real error

this is not solvable without a marker or really nasty hacks o track subsequent imports

the current code works as expected. Why not leaving it like this since your change seem to be comsetics only ?

can you give an example of a bad error ?

to correctly implement it we need the : separator back

with the separator the import specification is no longer ambigious,
and we can use one exact import, and an error will always be an error

an example of creating a wrong error would be something like the following:

there is a package, which does a wrong import in
we want to resolve the name

we'd get the error that foo has no attribute bar
