Hmm I wonder if we should print the entire module name in the case that the last segment is the same for both types
Because I agree, that error is confusing

Yes also more packages might get added to std lib from now on

I think it will once stdlib goes v1!

ooo
how can you use it tho? you have to have different name when importing the type

Unlikely I think

because you need to import the decode package then import the decode package in std lib to get the correct type

That's OK, I think I fixed it
