I don't think it's intentional, and it certainly feels like a bug.

Although I agree that there might be use in it, it's hard to tell if this
is a special case that is useful enough to break the rules. A hugely more
general feature would be user defined type conversions, for example, which
would make "public" work here and this case could become the compile error
that I think it should be.

Other opinions?
