   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
