As was mentioned in another thread, we agreed at the F2F that we
should be writing tests for test262 for features like Maps and Sets
that are implemented, even before they're described in the spec.
Unfortunately, I think only companies that have executed the
contribution agreement for test262 can contribute, but this seems like
a good place to start.  :)
