I don't see such functionality in Ant


Because Ant doesn't have a way to determine isDebugEnabled().
XmlLogger, for example, logs everything and ignores the command line
switches.  So the only "thing" which would know it is the listeners
themselves.

Since the listener API doesn't expose the verbosity - and changing the
interface is no good idea either - I don't see how we could do it.

I've always wondered how much overhead the verbose/debug log info takes 
up. It would make sense to determine the cost before addressing the 
issue. And, as you say, the only solution is changing the interface (or 
cheating, using reflection on the side).
