And then you can run it on a whole mess of code and verify that it’s
only different in the cases where you want it to be different (what
used to be an ERRORTOKEN or NEWLINE is now an NL because we’re in the

Maybe any compound statement header? e.g. if/while with lots of and/or
conditions, but more to the point it doesn't really make sense to make the rule
work differently for different types of statements.
Sure. People don’t bring that up as much because with it and while you can
already just use parens, but no reason they should be different.
And that raises a point: the if keyword can appear in other places besides the
start of a compound statement. Does tokenize.py have enough info to handle that
properly? I don’t know, and the answer to that might be a good proxy to the
question of whether it can be done in the real compiler without making parsing
complicated, even if it won’t prove the answer either way.
Keywords (reserved words) are special everywhere except in strings and
comments.
