How is a:b better than a..b? two dots are straightforward, unambiguous,well known.

I don°«t see a need for it. As for { °«ten°«: 10 }, I agree it°«s discussable if it°«s gonna evaluate to a string or a symbol. If it°«s a symbol you pretty muck kill consistency in the case other things will be acceptable on the left side (like {1: 1, 2: 4, {lol: °∆wut°«: 9 }, evaluate_this.method: °«the result').
