Thanks Tim, but it's more complicated than this.
It would be the sum of two errors, maybe a lack in
runIn{New,This}Context and sure a lack in my mind!
But the reality is that this code doesn't work for me (into a
runInNewContext):
var WIDTH =750;
var HEIGHT=300;
console.log(Util.inspect(this));
//Util is from require("Utils");
it prints {} when executed into a runInNewContext
Where are the objected stored?
I have discarded a fail in my code (=owned candidate?)

To be "exactly" like eval, use eval. What property about eval do you
need? "this" is set by how you call a function, it can change on
every call (except for bound functions). Closure scope in eval is
probably what you're talking about. I generally use runInNewContext
and pass in all the variables manually I needed from the closure.

I am working in a project that implements a basic plug-in engine.
I tried to use runInNewContext(...) and the rest of similar implementations
in VM module; but finally only was able to do using eval.
My fault is I don't understand well contexts, 'this' keyword and so, but I
could improve my knowledge if somebody ask this question:
How can emulate 'exactly' eval using only methods from VM module?
volunteers?
Thank you in advance, I had been working for 10 hours straight and I am not
able to think with properly XD
