When I try to use undeclared variable then I get exception. It's right. When I
try to use undeclared variable but it will be declared later then I get that
this variable is undefined.

Reproducible: Always

	alert(DCTOOLKIT_JS);
} catch(e){
	alert(e);
	var DCTOOLKIT_JS=1;//you can var keyword replace on const keyword.
}
Actual Results:  
I should get exception.

Expected Results:  
I get that variable is undefined.

Please don't file INVALID bugs -- instead, study ECMA-262 (Edition 3 is
available at http://www.mozilla.org/js/language/E262-3.pdf among other places)
to see why this bug is invalid.  Section 10 in particular is important.
