How does hack solve this? Do they have backtracking in their parser?
It was discussed earlier & Bob answered it, a T_LAMDA_OP is inserted
by a token token-pre-parser before hitting the real parser, see:

(Resending, because I accidentally forgot to "Reply All".)
So, if I'm understanding this correctly - this approach wouldn't
require backtracking, and would make the simplest syntax possible?

Well, I don't know really being a userland developer, but I'm sure Sara &
Bob knows. It's discussed in the "[RFC] [Discussion] Short Closures" thread
and I recall it was described as an ugly hack (abomination). Still Hack has
the functionality with type-hinting, default values and simple syntax.
