I needed to made a tiny change and I took the liberty of undoing a change I suggested as it looked terrible:

I have made one correction (a stuttered close parenthesis) that made the grammar not parse.
I have also adjusted the expression for function-application as my suggestion made it visually bewildering. This adjustment is now only a tiny change to your original version.

Also:

I made a correction to the Python3 renderer so that it handles undefined correctly and prints out line numbers to stderr to make it easier to diagnose problems
