Hi:

My point was that I think Joe Armstrong's view
might be robust, but I'm not sure it's always practical.

You can't directly compare that to the exception::what()
or event queue,
because he's talking about an environment where
each message (a new CA monitor, an error message, ...)
is passed between processes which can't share anything.

So the database posting a monitor and channel access queuing it,
or the exception thrower and the catcher,
would all be different processes,
pointers wouldn't work between them.
He also envisions some global garbage collector.

I think java is somewhere in between:
You can still share pointers between threads,
but only pointers to objects, not types like 'double'.
and you have garbage collection.
That's already easier to use than C/C++,
and you don't enter yet another string-related discussion
with every API that anybody suggests for anything.

But at the same time, java is already slower than C/C++,
and I wonder about the performance of Erlang.
