You're absolutely right. We should eliminate the 'assert' keyword (since the interpreter can and does ignore assertions in optimized mode), comments, and blank lines. Anyone with half a brain will see at once that they should obviously be removed. Anyone with an entire brain, of course, will appreciate them. >> It makes no change at all to the execution model of the >> language. > > Then why the *HELL* are type-hints an official part of the > Python language syntax?
