What happened?
When running the following command:
conda shell.posix blah
I get the following exception:
# >>>>>>>>>>>>>>>>>>>>>> ERROR REPORT <<<<<<<<<<<<<<<<<<<<<<
Traceback (most recent call last):

This is happening because we think that we have imported the exception class here:
Line 48 in d16eb29
But, we later re-import the exception class in this method:
Lines 280 to 345 in d16eb29
By doing the imports later, we must be binding the ArgumentError class definition to the local scope of that function. This is what causes Python to completely ignore and not use the class definition from the outer scope (i.e. the module's scope).
The fix is easy enough: we just need to remove those other import statements. But this reveals that we do not have enough coverage for this file 😦. Let's fix that!
