Example use case:

I want to check if the exception is of some instance and check that they have correct attrs. We can just do duck typing, but sometimes, we want to have a stricter check.

The following is a snippet that I was playing with in my mind:

>>> M.instance_of(YAMLCorruptedError) & M(path="params.yaml")

I also see that this API is going to complicate implementation, so we can brainstorm other ideas too to have composite matchers.
