Use a closure

[conradw, 2015/04/13 14:36:33]

This test was checking propagation of strong mode into a direct eval, which
doesn't make sense since direct eval shouldn't be allowed in strong mode. Tests
such as the one on line 11 check the other aspects of strong mode exercised
here.

   assertTrue(eval("function f() { 'use strong' } 0 == 0"));
   assertTrue(eval("eval('\\\'use strong\\\''); 0 == 0"));
 })();
