    More importantly for commercial purposes, C++. That's the competition.
    While it is unlikely that we will be able to get performance comparible
    to C++ on the first round, given your Sufficiently Smart compiler, it
    should be possible to approach it. Whether a Sufficiently Smart CLOS
    compiler happens, however, is again a question of priorities. 

I agree with you, but would like to point out that I don't think the
existence of method combination has any bearing on the issue.  I think
multiple inheritance and slot access are the areas that cause more
performance impact compared to C++.  Furthermore I think the real
performance issues are entirely outside of CLOS, in areas such as
garbage collection and other things that Lisp does for you but C++
does not, and in the fact that the performance comparison is likely
to be on C's "home turf", hardware that is highly adapted for C and
less well adapted for Lisp.
