Thanks. And do "we" know which one is the most common case or any
reason we won't have the same in ES6 ? I see both options as a win.
Having only the => version looks like a huge limit in arrow potential.
We went through the case analysis here, perhaps you missed it?

quoting:
"""
If the consensus is that two arrows are too confusing, and we must choose
to prefer either object literal or blocks, then the code I sampled suggests
that object literals as expression bodies are rather uncommon (only 16 out
of 5705 BTF candidates, or 0.2%).
// Not so bad...
x => ({ a: 123 });

This is based on Kevin Smith's quantitative study:

Please study carefully!
As noted many times, going back to the March 2012 meeting, we also
talked about -> but some on TC39 view it as "an arrow too far". See
