I totally forgot we currently run the lambda code model through the interpreter to obtain the quoted instance! I don't think we should modify the meta factory as i suggested, apologies for misleading you.

At some point I think we need to remove the dependency on the interpreter - so we explicitly validate the lambda code model and the operate on it directly to create the `Quoted` instance. (For specification I think it is important we retain the current lambda code model program behavior.)

In fact i am not sure it is worth doing anything lazy right now in subsequent PRs and a better focus of effort would be to remove the dependency on the interpreter. After that we can address lazy construction of models.
