Closing as lazy is a separate backend, not default.
from explorer.
The cool thing about a laziness is that the backend can actually be eager if it believes it is more efficient, although I doubt this is the case given immutability. For peeking, it should be very close to setting a limit and then executing the query, right? But it is probably important to keep it as its own callback, in case other backends may want to do optimizations (for example, maybe Ballista gets only local data when peeking?).
