Thanks to Sebastian for his help.

This appears to be a bug? Well maybe my bug. My input parameter was intended as an identification number and not unreasonably I called it “id”. Apparently I can’t call the parameter “id”. I can call it “ix” and grc will find it. What on earth?

Help on built-in function id in module __builtin__:

id(...)

    id(object) -> integer

GRC runs in Python. It outputs Python code. You tried to use a reserved Python keyword.

It is *theoretically* possible for GRC to identify "stuff" that will later cause you problems at runtime due to Pythonisms.  But that would *vastly*
  increase GRC's complexity, and it would be error-prone, and "false positive" rather a lot, it's simply not practical.  GRC could also have its own
  "language" for evaluating expressions, rather than use Python.  That would come with its own set of surprises and gotchas, so, better to use
  a language that is already well-developed, well-understood, and with well-defined semantics.

There's no real way to get around the fact that, at the end of the day, you're programming, and thus run into all the same "gotchas" that
  "conventional" (is there such a thing any more) programmers run into.
