* 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."
