talks about having multiple alias thises per type.

What is the reason it hasn't been realized yet?
I don't know. While we're getting closer to having everything in TDPL
implemented correctly each release, there's still plenty of stuff left to do,
and no one has tackled the alias this issue yet. I expect that it's not an
entirely easy thing to fix and that other stuff has been higher priority.

The major thing being tackled this release has been const-correctness, and
it's not done yet (in spite of there now being a beta for 2.059). I believe
that that's been one of Walter's major focuses this release cycle, and I
wouldn't really expect him to tackle anything else major until Object's const-
correctness been sorted out. Nothing is stopping someone else from doing it,
but no one has. Plenty of other stuff has been fixed though.

To clarify, I mean to ask whether there are any design flaws in the
strategy of having multiple alias this in one type, or whether it is
purely an issue in the implementation (i.e. just plain hasn't been done
yet)?
