when the Function is created by the primitive, its current context is stored, be it the interpreter object or the enclosing function. at this point, shoulnd't be the information available whether the function could have been closed?
is this check correct?:No. you would have to check that the function referenced no variables in all enclosing contexts.
what kind of function would have more than one enclosing contexts? I've had the impression that the context encloses everything that is relevant already.
