Comment out the print statement about underflow.  (This only seems to
happen when you use a non-keyword argument after a keyword argument,
and in this case you also get a syntax error.  I fully suspect that
the underflow is caused by the code that stops generating code when it
detects the syntax error, but I can't find the culprit right now.  I
know, I know.)
