You may find this difficult due to ambiguities (bitfields and range based
for loop) with existing c++syntax...

Not really. Clang isn't designed to allow pluggable arbitrary language
extensions. Astconsumers are just for pluggable language consumers, they
don't get to change the language.

If you're changing the language you're going to have to change clang's
parsing and sema layers directly.
