That is a depressing bug report, and really comes across as people who
don't use networking commenting on the requirements of people who write
networking code.
It's good to see that the idea was getting a bit more treatment last yeat.
I added the following note to that issue.
"
struct.pack, not mentioned here, is a binary bytes formatting function.
It can do ascii bytes mixed with binary octets. It works the same in
Python 2 and 3.
Str.bytes does two things: convert objects to strings according to the
contents of field specifiers; interpolate the resulting strings into a
template string according to the locations of the field specifiers. If
desired bytes represent encoded text, then encoding computed text is the
obvious Py3 solution.
For some mixed ascii-binary uses, struct.pack is not as elegant as a
bytes.format might be. But I think such a method should use struct
format codes within field specifiers to convert objects into binary
bytes rather than text.
"
Note that struct codes include s = C char[] = Py bytes of possibly
unspecified length copied unchanged.
