I don't buy this total "relativism". It smacks of the "Turing
equivalent" arguments.

I suppose you are correct here. I'm here because I still do follow
(at least in passing) how Ada is doing and what it's followers are up
to. I try not to get into these things, but the comment from J.Coffin
comparing Lisp macros to a "preprocessor" was too much to ignore.
It's sad really how very little people here have even the ghost of an
idea of what something like Common Lisp is, can provide, and can do.

Well, now _that_ is certainly on target.

Lisp is not really a functional language, though it can be used as
one. It is very much multiparadigm.

This again sounds like a TE argument and so not particularly good.
The key thing aboug Lisp is that it is a programmable programming
language and thus can incorporate at any point any construct from any
language seamlessly and transparently into it. Does that make it
_necessarily_ superior to anything else? No - that typically is
heavily context dependent. But after having analyzed and used all
these "lesser" languages it is clear to me that in _most_ cases it is
definitely superior. Nobody here is going to believe any of this.
Then again, next to nobody here even has the ghost of a clue about the
facts that would undermine their belief.

No, I meant expressive capability also called expressivness, or
expressivity. Turing equivalence is totally irrelevant. If it had
any meaning in such discussions we would all be toggling in programs
as 1' and 0's at consoles.

Yes, indeed. This is very on target and is at the heart of the issue.
Which brings us full circle to the point here that the differences
being argued, from the perspective of Lisp (or Smalltalk) are so small
as to be meaningless.
