It does already, though. For example, there's not a clean way to mock
something that returns closures, which is probably more common than
something that returns exceptions. If returns() is given something that
happens to be a lambda, it doesn't return the lambda (which is what you'd
normally expect), it calls it and returns its value instead. I'm just
suggesting adding to that concept:
when its a Proc: call the proc, return the result # Existing behavior
when its an Exception, or an instance of an exception, raise it # Additional
else return return_value
I do see your point though - I'm not convinced this is worth arguing
strongly for, but I do think it fits well with the current code.
