Hi!

As far as I can see ECMAScript requires that ++0 should produce 
RuntimeError, not SyntaxError. So, for example, the following should be OK:

var f = Function('++0')

and only during call to f RuntimeError should be generated. Microsoft 
JScript and KDE JavaScript implementation follows this while 
SpiderMonkey behaves much saner IMO and report SyntaxError during 
parsing. But does ECMA-267 allow this early error reporting?

Regards, Igor
