Now you have me thinking.  For Apache 2.1 (perhaps 2.0) I'd like to see that
particular nonsense go away.  I sympathize with André's observation that it's
useful, but what he wants to do can be accomplished with

<IfDefine NEVER>

which serves the same purpose, but it much more legible.

You point out that containers that expect args (e.g. not <Perl> blocks) can 
be very difficult to debug in any sort of dynamic (mod_macro) sort of config
environment.  But also consider that many conf rewriting tools could probably 
crack under the strain of parsing such <IfFoo> containers, if they specify
no argument.

On the balance, for 2.1 forward we should disallow <IfDefine >.  It's a coin
toss to me if we continue to accept them in 2.0 - so I'd argue the principle
of least surprise.  Disallow in 2.1, but continue to allow in 2.0 <IfDefine >.

That would be goodness!
