michael@0:  * Brendan: "The test seemed to require something that ECMA does not
michael@0:  * guarantee, and that JS1.4 didn't either. For example, given
michael@0:  *
michael@0:  *             dec2 = "function f2(){1,2}";
michael@0:  *
michael@0:  * the engine is free to decompile a function object compiled from this source,
michael@0:  * via Function.prototype.toString(), into some other string that compiles to
michael@0:  * an equivalent function. The engine now eliminates the useless comma expression
michael@0:  * 1,2, giving function f2(){}. This should be legal by the testsuite's lights."
