Ok, cool. I don't really like global stuff like that either. But,
some libraries (beanutils for one) do that kind of stuff. I like the
idea of having your own instances of this and I like the idea of the
feature. Very cool! Also, the varargs feature would be very nice.
They've already made MessageFormat use varargs in 1.5, so it would
fit.
