Ha! I knew I'd find a way to get a correction on Diane if I waited long enough :)
Actually the back-door hack for <available> is being left in (just with a nasty message if you overwrite a propertys value using it) - that was the curreent consensus, unfortunately. This may change before the release of 1.5, but thats how it exists in the nightly builds now though.
