I'd find that a bit astonishing since other punctuators (like prefix "-" and
"+" and postfix ":") don't work that way. If "?" did become a
no-space-allowed identifier suffix, it might be nice to do the same thing
for ":" property names in object literals since that would let you use
reserved words as property names (or labels, I suppose) without complicating
the parser:
{ if: 123 } // ok since "if:" becomes a single PropertyName("if") token and
not IfToken followed by ColonToken.
