The PyCall function wrapper could add a func_code (or __code__ in Py3) attribute that returns an object with at least some of the attributes of the Python func_code, e.g. co_argcount (the number of arguments), co_filename (the file where it is defined), co_firstlineno (the line number), co_name (the name of the function).
An inherent difficulty is that Julia functions can have multiple methods with different argument counts (and defined in different files etcetera), but I guess we could look at methods(f) to see if all of the methods have the same number of arguments, or return the maximum number of arguments or something. (PyCall PRs welcome, of course.)
