Why can't we call map.keys() directly?  Is this trying to make JSCompile happy?
Or is it because we want to return a copy of the keys instead?

[John Williams, 2015/07/20 21:43:10]

I need a Set (so I can test for membership), but Map.keys() returns an Iterator.
 All the typecasting is necessary because the externs files don't declare that
Iterator extends Iterable.

Anyway, this function is no longer needed in my latest patch.
