File Name: tostring-1.js
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.
