* Date: 11 August 1998
* REVISED: 04 February 2001
* (changed the comma expressions from trivial to non-trivial)
* Author: pschwartau@netscape.com
*
* Brendan: "The test seemed to require something that ECMA does not
* guarantee, and that JS1.4 didn't either. For example, given
*
* dec2 = "function f2(){1,2}";
*
* the engine is free to decompile a function object compiled from this source,
* via Function.prototype.toString(), into some other string that compiles to
* an equivalent function. The engine now eliminates the useless comma expression
* 1,2, giving function f2(){}. This should be legal by the testsuite's lights."
