How to use globals correctly?

[Robert M. Münch via Digitalmars-d-learn]

Hi, I'm feeling a bit dumb but anway...

For hacking prototypes I mostly create a class to store all kind of 
values. Then I create one global instance of this class and use it 
everywhere. Pseudocode looks like this:

class myClass {
        myMemb1;
        myMembN;
        this(){...}
}

__gshared myClass myObj;

main() {
        myObj = new myClass();
        func1();
        ...
}

func1(){
        myObj.myMemb1 = ...
}

If I use VisualD and add a watch on myObj, I don't see anything just a 
"identifier myObj is undefined". Not sure if this is because of some 
threads running (using the D RX framework).

So, some questions:

1. Are myMemb1..N TLS or __gshared as well?

2. How to best implement a simple global to keep track of values (with 
support for threads)?
