[Pythonmac-SIG] Is the menu enabled?

The above sequence should work...the problem is that, *probably*, the
layout of the contents of a menu handle and a menu bar (handle) will be
unknown in Carbon:  they are likely examples of the opaque data structures.
There should be accessor functions to replace direct access per the struct
definition.

Likewise, a WindowPeek no longer peeks into the structure of a window
record, etc etc.

Unfortunately, I know no details...my opportunity to attend a meeting in
Seattle a couple of Saturdays ago where I would have learned something was
foiled by the fact the the boss was in California...one of needs to be
somewhat nearby to kick the servers if necessary (our main machine just
passed one year of continuous operation today...we don't have to kick that
one much...BSDi Unix.  Unfortunately, a couple of days ago I accidentally
killed the Apache process which had been running on the machine, but not
doing much...the web servers are elsewhere, since December 8 1998).
