I don't believe this is legal. Didn't we agree w to support [ ]
property keys that evaluate to symbols.
I don't know what the agreement is, but that would be wise to forbid
strings in [ ] propert keys given that ES6 introduces Maps which seem
to be a better host for dynamically generated string keys.
What?
Maps are for *abitrary values* as keys -- any type.
Objects have string-equated keys so far. In ES6 we sum symbol | string
as the property name type. There is no problem with the o = {[n]: v}
syntax for computed property name n (an expression, we argued about
wither /Expression/ or /AssignmentExpression/ but I forget the outcome)
resulting in either a symbol, or else a value equated to a string as in
object literals today.
