What was acknowledged was that CEDET does not implement the full C++
standard, that's all.  It remains to be seen how important that is to
the Emacs users at large; obviously, CEDET developers didn't think
what they had was useless.  Your needs are not the only ones, and not
necessarily representative of those of others.

Because Clang was designed and implemented as a compiler, first and
foremost, and not as a CEDET backend.

How many times we will need to go through this before you will
understand that hand-waving and unsubstantiated claims are not
convincing?  These repetitions serve nothing else but discouraging
people for trying different approaches -- is this really your goal and
your agenda?
