If you have access to the source of the function you want to call (and know
what kind of data types it wants in its args) you can raise something else for
bad parameters, eg:
class ArgTypeError(TypeError):

However, this results in bugs in the server code that would cause
TypeError to reply to the client that it had the wrong number of args,
