does try really need to be a keyword?

[Gribouillis]

i could, instead, argue, that ":" isn't needed, in general (and can be optional for enhancing readability for humans)

I proved that "." is not needed in python by implementing a program that adds the dots automatically. If you also remove the ":" and the fact that "try" is a keyword, it may stop to work. I'd much prefer a python without "." than a python without ":".
