Cycling binding that is not cyclic detected

[Martin Sjölund]

If M.id is renamed to M.idx, the following code works. Seems we do not find out if an identifier comes from within the function scope or not.

model M

function f
  input Integer id;
  output Integer o := id;
end f;

function g = f(final id=id);

Integer id;
Integer y = f(id);
Integer z = g();

end M;
