> arrow "keyword" a very sensitive choice

I think you meant 'sensible' there.

I actually find the cs arrows a lot more useful than the es6 short-hand function definition, because a lot of the time I want to do be able to do composition, and the es6 one always binds the scope to where it's defined.

I love named functions otherwise, which ease debugging and understandability. I actually don't care for implicit returns, not just because i prefer being explicit, but because it's the cause of some very weird bugs at times.
