This isn't the only way to proceed. I'd encourage someone wanting to
do this to branch GCC and implement a rough cut of the feature. That
will provide useful information about the amount of work likely to be
needed to complete the task. Also, it will provide the opportunity to
try out the language feature to see how well it works in practice.
