def getargspec_permissive(func):
    """
    An `inspect.getargspec` with a relaxed sanity check to support Cython.

    Motivation:

        A Cython-compiled function is *not* an instance of Python's
        types.FunctionType.  That is the sanity check the standard Py2
        library uses in `inspect.getargspec()`.  So, an exception is raised
        when calling `argh.dispatch_command(cythonCompiledFunc)`.  However,
        the CyFunctions do have perfectly usable `.func_code` and
        `.func_defaults` which is all `inspect.getargspec` needs.

        This function just copies `inspect.getargspec()` from the standard
        library but relaxes the test to a more duck-typing one of having
        both `.func_code` and `.func_defaults` attributes.
