constructor() class method keep's throwing an exception

[PikioopSo]

The exception is:

*** ReferenceError: |this| used uninitialized in anonymous class constructor ***

When I create a class using:

xtag.create( class extends xtag.extensions(myExt){
constructor() { }
} );

It throws the error. When the constructor() method is not used it does not appear. I believe it is a scoping problem.

I found another missed placed token in the script I was working on. @csuwildcat .

Thanks for all the help.
