For when/if views ever become considered to be a good thing for builtin classes, etc, may I suggest that the following syntax be reserved for view creation:

obj{start:stop:step} mapping to something like: def view(self, slice) So if you really want a string view, use: s{1:2} instead of: s[1:2] I don't think the syntax is currently legal, and I don't think it could ever be ambiguous - anyone think of a case where it could be?

OTOH, it is very subtle. I had to lean closer to the monitor before I could even see the distinction you were making! (OK, some of that is due to less-than-ideal fonts plus failing eyesight, but the point remains...)
