Even parsing issues aside, I don't like postfix better. It is easier to
miss, especially if ? was possible on patterns, not just properties.
Consider:
let {the, that: {x, y}, those, theirs: {what, why}, thus}? =
callSomething()
How easy is it to miss the final '?' when looking for the binding of 'x'?
But even on longish property names it can be a tad too easy to overlook:
let {what, why, whatTheHeckIsGoingOn?} = callSomething()
