Using exceptions is totally common, but this seems to raise/catch/log 6 errors each time it tries to parse a `for` statement. I'm a noob when it comes to compilers, but maybe a token -> function dictionary would be a better approach?

That does sound a bit extreme. (I freely admit I went by this description and never looked at the parser code myself, though some other portions I did read were pretty normal Python.)
