Description Ondrej Brejla 2015-04-21 13:05:27 UTC 
Imagine this snippet:

define([
], function() {
    var foo = new Foo();
});

Foo() is not violet even though Foo is not declared anywhere in a file. 

Imho it should have some "semantic" marker to be clear, that someone tries to instantiate "global/undeclared" thing. 

Because it is just a mistake in most cases and someone just forgot to declare/import right constructor function ;) Thanks a lot!
