wrapper in state?

Ok, after analyzing things it appears that wrapper should not be in proxy
state, because that way it generates spurious pulls:

e.g. in order to pull x we need wrapper, so we pull wrapper, so we need
wrapper, we don't pull it now because we were already pulling it, so we get
wrapper, to get wrapper, to pull/get x.

I will change Attrib to allow for plain attributes (withouth '_') to fix this.

regards.
