I hate the CoffeeScript deviation, though. It's just confusing for
anyone who ever learned that fat-arrow binds |this| and thin-arrow
doesn't.
True. On the other hand, "all arrows bind |this|" is also quite
simple and easy to remember.
Yes, and I kept the part of the proposal that allows |this| as a leading
arrow formal parameter, including with parameter default value. This
suggests a slight variation on the strawman, per your suggestion:
x -> { return this.x; } // lexical this for thin arrow
x => this.x // as for fat arrow
(this, x) -> { return this.x; } // dynamic this, five letter syn-tax
(this, x) => this.x // ditto for the expression-body form
IOW we make fairly concise, orthogonal syntactic tools for composing (a)
lexical vs. bound |this|, and (b) block vs. expression (including object
literal) body.
(I used your suggestion of the C#-like shorthand for
single-formal-parameter above -- nice!)
