>Summary: Bit support in "array" module

Initial Comment:
I think the standard "array" module should support 
single bit arrays.

In fact, would be very nice a supplementary addition 
to support arbitrary bit size arrays (for example, 5 
bit elements). Of course, single bit should be 
optimiced, since bitmaps management is a frequent task.

While bit arrays would indeed be nice, the array module's
internal design makes it impractical to add it there. For
small-to-medium size bitmasks, I recommend using long ints
(x<<i is a bitmask for bit i, use & and | and ~ to set and
clear bits). If someone wants to implement a fast bitmap
type in C, let them submit an extension to the patch
manager. Closing this request as "won't fix".
