Scopes (PushScriptObject / BlockScope)

Hi,

I'm trying to add different scopes to a VsaEngine and change variables
values in these scopes at will...

I'm currently doing:
eng.SetOption("fast", false);
ScriptObject so = new BlockScope(eng.ScriptObjectStackTop(),"scope1",1);
eng.PushScriptObject(so);
Eval.JScriptEvaluate("var v = 1;",eng);
ScriptObject so2 = new BlockScope(eng.ScriptObjectStackTop(),"scope2",2);
eng.PushScriptObject(so2);
Eval.JScriptEvaluate("var v = 2;",eng);

It's working fine since "v" exists twice once in "scope1" and once in
"scope2" with two differents values.

Now from here, here is what I would like to do:

Eval.JScriptEvaluate("scope1.v = 3;",eng);

Basically how can I reference directly the variable "v" in the "scope1" ?

I thought that BlockScopes names would be available as global properties but
they are not ...

Am I erronously using BlockScope or PushScriptObject ?

Is there any other/better way to create scopes ?

Thanks!
