Well... I am kind of at a disadvantate here because the decision has already
been made. It would be hard to migrate away from this even if I was right.
The theory at least is that you never use a precompiler. Just just if () {} out
your code because it REALLY pays off in code maintenance in the long run. The
IBM Log4J stuff is a good example. You leave the code the same but when you
deploy you just turn off the debug and only get about a 0.5% lag. Worth it if
you consider the time it will take maintaining this code in the long run.
.... there is a small section about this in the original JLS I believe....
There is also a SUN JSR for this stuff about assertions. The assertion stuff is
a language extension so that you can exclude it on compiles.

This is in the SUN Assertion JSR.
http://java.sun.com/aboutJava/communityprocess/jsr/asrt_prop.html
... The documentation is public but we certainly can not participate in its
development because of SUNs *stupid* IP restrictions in the JCP. There are good
ideas here though and since this stuff will eventually make it into JDK 1.4 I
would say it should eventually belong here.
