This is good work, but I don't think every function that doesn’t use
'this' is a supporting use case for bound-this functions, though. Many
functions are like this:
panels.each(function (p) { p.fadeIn(); });
and that function would not benefit at all from being converted to a
bound-this function.
Depending on syntax, it could be rewritten like this:
panels.each(p => { p.fadeIn(); });
which would offer gains in brevity, even though lexical this is not
used. I'm assuming that for all "non-method" function expressions, BTFs
The question here is, if there is a observable difference in performance
between BTF and non-BTF, and not to allow the shorter syntax only for
the less performant one (either only for the more performant one, or for
both), because shorter form will be used also when not needed.
would be preferred for this reason.
