There are a number of generic implementations of these sequence algorithms:
Aren't all these implementations works with iterables and iterators?

Maybe it's time to add a new module for sequence-specific functions
(seqtools?). It should contain at least two classes or fabric functions:
- A view that represents a sliced subsequence. Lazy equivalent of
seq[start:end:step]. This feature is implemented in third-party module dataview .
The result of itertools.islice() is not a sequence.
- A view that represents a linear sequence as 2D array. Iterating
this view emits non-intersecting chunks of the sequence. For example it can be used for representing the bytes object as a sequence of 1-byte bytes objects (as in 2.x), a generalized alternative to iterbytes() from PEP 467 .
toolz.itertoolz.partition() is just a generator.
