    Section:            Function.toString
    Description:

    Since the behavior of Function.toString() is implementation-dependent,
    toString tests for function are not in the ECMA suite.

    Currently, an attempt to parse the toString output for some functions
    and verify that the result is something reasonable.

    This verifies
