It's incovenient, but it works. I often end up converting the
string representation to/from a list of integers.

Bit twiddling didn't used to be difficult, but it's getting
more so. :( Programs that used to be fine are now throwing
warnings about shift operations, hex constants, and things like
that.
A while back, somebody wrote a pure-python fixed-length integer
class that looked like it would be handy. A C implimentation of
byte arrays would be very handy, since then you wouldn't have
to convert back and forth between strings and lists of
integers.
The combination of a C-language byte-array and C-language
fixed-length integer operations would kill.
