michael@0:    Description:
michael@0: 
michael@0:    Since the behavior of Function.toString() is implementation-dependent,
michael@0:    toString tests for function are not in the ECMA suite.
michael@0: 
michael@0:    Currently, an attempt to parse the toString output for some functions
michael@0:    and verify that the result is something reasonable.
