Actually, it's a bit irritating that javac doesn't implement those and
a few others (particularly __CLASS and __METHOD). They would be very
easy to implement within the language, without the need for a
preprocessor. But certainly the need for them is reduced by the
generally good to excellent traceback info available in most
environments. Just a little lacking in logging situations.
