Problem:
4.17. Implement array.array.{index,remove,count}
[tim_one@email.msn.com] array.array objects currently
don't support list's index, remove or count methods,
but could <wink -- but once index is written, the other
two could build on it>.
Later: array.array doesn't support the new(er) list.pop()
either, although that one is still (1.5.2a1) experimental.

Solution:
adapt listindex,listremove and listcount to arrays
I chose rather to adapt all three than to build on index
