Example:

  var o = {
    foo() { return 10; },
    bar(a, b) { return a + b; },
    100() { return 100; },
    'method'() { return 0; },
  };

This is pretty much identical to class methods, just for object literals.

[PATCH] Proposed Fix

Requires a patch not yet landed (the PutType stuff).

[PATCH] For Bots

[Joseph Pecoraro]

It should be trivial to extend this to support computed methods as well:

  var o = {
    ["foo" + "bar"]() { return 10; }
  };
  o.foobar();

Since it is highly related, I'll put up a new patch.

[PATCH] Proposed Fix - With Computed Method Names

Still requires a previous change, so this won't build on the bots.
