Python has genericity built-in--right?  Is
that exactly the point here, or is there some-
thing more or less to it?

I've been thinking about I/O.  Is Java *wrong*
(in the sense that, say, inter-module communi-
cation through FORTRAN common blocks is an
unacceptable hazard), or just different, in
this regard?  Myself, I much prefer event-ori-
ented programming, and think that threads are
generally dangerous in the hands of amateurs;
on the other hand, I find Java's I/O just a
*different* programming model, one not inher-
ently inferior.
