Terry J. Reedy added the comment:
I think 'iter_unpack' is deceptive and wrong for the following reason. Up to
now, 'ixyz' or 'iterxyz' or 'iter_xyz' has meant a version of 'xyz' that
presents items one at a time rather than all at once in a collection object
(usually in a list). Unpack returns a tuple, but the new function would *not*
present the members of the tuple one at time. Instead, it would apply unpack
multiple times, yielding multiple tuples. I would call the new thing
'unpack_all' or 'unpacker' (the latter works especially well for an iterator
class). An unpacker is a person or machine that repeatedly unpacks. (I was once
a bottle unpacker for a college summer job ;-).
struct.unpacker(fmt, buffer)
Return an iterator that repeatedly unpacks successive buffer slices of size
calcsize(fmt) into tuples according to the format string fmt. The buffer length
must be an exact multiple of calcsize(fmt)). (? Not clear from text
description. Add param to allow remainder?)
