Still afraid of this issue due to the hugge thread is spawned last time,
but I _still_ feel it was unresolved last time. Each of my posts asking
for a breakdown of "what is currently difficult in the current system"
and "proposals for how to extend the current system" went ignored. I
would still love to see that, because I really do think there are some
use-cases which could be helped out.
This is just a ++ for further /intelligent/ discussion on the thread.
(and may noone ever mention named numbers within it ;)
