I agree it doesn't make it the best design. But I don't think numeric coding
is used *just* because its space and time efficient - it's also more
intuitive. I don't think log4j is like it is because of platform

I'm not sure "optimal" can be applied in this kind of context, in the true
sense. Depending on the kinds of applications you and I work on, "optimal"
for you might be different to "optimal" for me.

Please don't get me wrong. I'm not averse to using a new approach just
because it's new, nor is the present approach chosen because of "old/small".
The posts in this thread have got me thinking, but I don't know how long
it'll take me to "get it". I *still* can't see what it is you'd like to
achieve, but which you can't with the current functionality. A specific
example from a real application would sure help :-)
> Please look closely at the TIBCO subject-based messaging
Thanks. I will, time permitting - I'm not intimately familiar with the TIBCO
system but IIRC their messaging *is* the product - it's a full-blown
middleware layer. Probably much bigger than I can develop in my spare time
Regards, and thanks for your patience...
