Maybe it's time to add a new module for sequence-specific functions
(seqtools?). It should contain at least two classes or fabric functions:

1. A view that represents a sliced subsequence. Lazy equivalent of
seq[start:end:step]. This feature is implemented in third-party module
dataview [1].

2. 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 [2].

NumPy slicing and reshaping sounds like it satisfies these requirements. Does it not?
