If you are looking for a lazy uniq that works on non sorted
ranges, I implemented one not to long ago:

That sounds like the kind of thing I was looking for. I'll
take a look, thanks!
Well that one does allocate, because it keeps track of which
values have already been seen.
Yup, just noticed that >.<
Of course it only allocates when the actual result is used, so
this will probably be more efficient if you only need a small
number of unique results or need to keep the unsorted range
around/intact. Sorting without allocating and then using uniq
should indeed be more efficient in other cases.
Did you try different SwapStrategy values in your original?
