     24  *  Description:  (SEE REVISED DESCRIPTION FURTHER BELOW)
     25  *
     26  *  The global eval function may not be accessed indirectly and then called.
     27  *  This feature will continue to work in JavaScript 1.3 but will result in an
     28  *  error in JavaScript 1.4. This restriction is also in place for the With and
     29  *  Closure constructors.

     40  *  Indirect eval IS NOT ILLEGAL per ECMA3!!!  See

     44  *  ------- Additional Comments From Brendan Eich 2001-01-30 17:12 -------
     45  * ECMA-262 Edition 3 doesn't require implementations to throw EvalError,
     46  * see the short, section-less Chapter 16.  It does say an implementation that
     47  * doesn't throw EvalError must allow assignment to eval and indirect calls
     48  * of the evalnative method.
