100% agree on this point. The community needs some ways to keep up to date
with those new compiler versions. I know it's hard since we work on
different projects which usually needs some kind of stability (in the
product and in the development process) so we tend to stick with a reference
compiler that we know works.

However, if we don't keep up to date with those new compiler version, well
fall in some intensive bug chasing session... and debugging at the assembly
level is not that fun.

And it's a cycle, we test the new compiler version, we find bugs, we get an
improved compiler which, with a nice side-effect, may solve other bugs.

3.0 ? That's good news in terms of technology advance... however I fear some
late nites chasing bugs generated from that new version :)


Cheers!
