It's absolutely negotiable. I don't need to defend this anymore – look at the number of yes votes Bob's proposal garnered despite some very glaring concerns about other aspects of the RFC. > >> Again, if use() is a pain then auto-importing the >> used variables is a good solution.

You are assuming that "I think the current syntax is > verbose" is synonymous with "I think having to list captured variables is > annoying", but there are people who do not take that position. You are capped to saving about 5-7 characters no matter what you do with this functionality. This is nothing compared to what is proposed if you save just one single-letter variable import with fairly customary spacing: $versionA = function($x) => $x + $y; $versionB = function($x) use($y) { return $x + $y; }; That's a 27 character difference (well, 24 if you use tab instead of spaces). Twenty-seven. Please think about that before you respond again.
