What do you mean by "current"? Are you proposing to legitimize the dynamic
scoping behavior demonstrated by your example?
If all major browsers agree on this bizarre behavior, we will indeed be
stuck. But if some existing browsers use lexical capture (i.e., return 1 in
both cases), then ES-Harmony should feel free to specify that. What do each
of the major browsers do?
