From the spreadsheet linked in Kevin's mail above, it looks like 81% of function expressions had statement bodies, and >50% did not reference this. While these were cast as BTF candidates, they are also just as much candidates for benefitting from no-frills function shorthand. There are a couple of separate topics being tackled simultaneously here (1) 'function' is cumbersome (2) 'var self = this' is cumbersome (3) '{ return }' is cumbersome. We can separate concerns if we want, and solve only a subset of these problems. From Kevin's analysis - solving (1) helps 100% of function expressions, solving (2) helps 45% of function expressions and solving (3) helps 9% of function expressions. That's the basis of my claim that just solving (1) would be a big win. Note: Kevin had a follow up where the % of functions with statement bodies was revised, using examples like 'text => { console.log(text) }'. Since these don't really hit the 'cumbersome' path in case (3) above, I'm quoting the original numbers which characterized where problem (3) was a current pain point.
