to think we should be adding lazy versions of functions where possible rather
than versions with OutputRange parameters. It's more flexible that way and can
result in even fewer allocations than even OutputRange parameters would have
(i.e. you can have chains of lazy operations and only allocate on the final
step, or not at all in some cases).
Laziness isn't appropriate or possible everywhere but it's much easier to go
from lazy to eager than the other way around.

This is not comparable. Lazy input range based solutions do not make it possible
to change allocation strategy, they simply defer the allocation point. Ideally
both are needed.
They move the allocation point to the top level, rather than the bottom or
intermediate level.
