Checking function calls

[Ravi Teja]

You can match if the list contains the legal number of arguments with.
func_variable.func_code.co_argcount

Type checking arguments has to be done manually since Python is a
dynamic language. Perhaps, you could try some typechecking decorators.

>From the docs, this one raises TypeCheckError (not TypeError), so you
should do fine.
