It is not surprising that methods that do not exist in Iterator
are not implemented in StreamExt
.

Also, please describe the specific behavior you need. dedupe
has at least two patterns (contiguous elements vs all elements).
In the context of streams, the method which I believe makes most sense is deduping sequential elements, not all elements, as this is an operation more suited for doing in a collection. However, deduping sequential elements can be very handy for implementing signal-type interfaces that are only triggered when an element actually changes.
I understand thinking of streams as just the future equivalent of future-backed iterators (because that seems to be the design intent), however, I think they can be slightly more, mainly, well, streams of data that can be altered, filtered, diverted, etc., in ways an iterator might not be.
At least that's my opinion.
I am surprised this is something not currently implemented for
Stream
, unless I am missing something. It would be a great addition.
