I agree. I would not exclude namespaces.
What I would add is a required "explicit" on all single-argument
constructors. We want all conversions to be explicitly specified.
Do we have a warning for this we can use?
I would like to be able to use function overloading.
For the start we'd want to use -fno-exceptions -fno-rtti for stage2
and stage3.
Oh - and we didn't yet decide to switch to C++ as implementation
language. Did we?
Thanks,
