Test call
=========

Test the call method::

    >>> from pyloader.invoke import call
    >>> options = {'badarg': 'bar', 'a': 7, 'b': 9, 'c': 10}
    >>> def foo(a, b=1, c=2): 
    ...     return a + 10*b + 100*c
    >>> foo(7, 9, 10)
    1097

You can't call methods with bad arguments OOTB in python::

    >>> error = None
    >>> try:
    ...     foo(**options)
    ... except TypeError, e:
    ...     error = e
    >>> type(error)
    <type 'exceptions.TypeError'>

But you can with call::

    >>> call(foo, **options)
    1097
