Well I suppose that technically this would be a compatible
extension, but I cannot imagine anything more inappropriate
than having BOTH mechanisms in the same language, that
would just be a confusing mess, so I am not FOR A MOMENT
suggesting a change to the language here, merely musing
about what might have been.
And I must say, that the argument is not clear. In
particular, especially if you have the ability to separate
off private parts physically, e.g. into a separate file,
there are tremendous advantages in having the private part
be separate. For example, it is very typical that the spec
proper is target dependent, but the private part needs
specialization.
So I am not at all sure that I am clearly in favor of my
original note, quoted above, here. The issues are basically
that this would simplify the semantics considerably, but
there would be a real cost in abstraction capabilities.
