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