   454 /* func_new() maintains the following invariants for closures.  The
   455    closure must correspond to the free variables of the code object.
   456 
   457    if len(code.co_freevars) == 0:
   458        closure = NULL
   459    else:
   460        len(closure) == len(code.co_freevars)
   461    for every elt in closure, type(elt) == cell
