Thanks Rick. And I suspect there is no way to reclaim that strictness, right?
Asking because it could be useful in cases like this :
module "Safe" {
"not use strict";
export function eval(str) {
return std.eval(str);
}
}
And so if I will call:
Safe.eval("gvar=666") ;
it will not pollute global namespace.
