Hey, I didn't say it was a good thing to do, I just pointed out that
technically you can override a macrodef'ed task just like any other
task.

I'm not convinced that we need something like this at the task level,
while I agree we need some better support for it at the target level.

Back during the Ant2 discussions we have been talking about adding AOP
like features to Ant at a well-defined "pointcut"s like target and
task invactions. This may be overkill, though.

Having something like before/after/around advices (where around is the
same as an override that doesn't change the dependencies list) may
suffice and leave overwriting the whole target definition to the worst
case.
