Details

Iterators use self-hosting to initialize prototypes. That means that it installs methods by looking them up using GETINTRINSIC. This means that all thus-installed methods get cloned eagerly.

Now, this isn't as bad as it sounds, because all of this only happens upon first instantiation of a legacy generator.

Still, I can't think of any good reasons for GETINTRINSIC not to do lazy-cloning, so it probably should.
