I strongly suggest that you have at least a draft standard before you
start, and that you think seriously about corner cases and interaction
with other language features before you start coding (and let others try
to find flaws with it as well).  The fact that this hasn't always been
done has contributed to lots of problems with GCC extensions in the past,
and the implementation will be cleaner if you identify as many issues
as possible up front.
