I've greatly enjoyed writing CoffeeScript, but am concerned that over the long term, it will fall behind javascript in terms of feature support.

The [Babel][1] transpiler (formerly 6to5) and tooling like Facebook's typechecker, [flow][2] have large teams and a rapid pace of development.

I don't want to miss out on cool features like generators, let/const, etc just for CoffeeScript's lovely bracket-less code.

Ditto. I don't think the CoffeeScript philosophy as it stands will ever have it keeping up with the pace of JavaScript proper at this point. Within the next year, I think our company will be migrating back to the land of curly braces. The charms of CoffeeScript just aren't worth missing out on all the great stuff coming to JavaScript as of late.
