Fair enough, but you should notice that your entire argument seems to based
in the axiomatic statement that I remarked above.
IMO, the bottom line of this discussion is that Andrei and you think that
compile-time programming differs from run-time programming so much that, as
you said, the conventional run-time needs (such as efficient random access
time, head-tail appending time, insertion time, permutation time, etc...)
don't apply to compile-time.

You have to prove, or at least, explain a lot more deeply, this point
precisely. Why different sequence-types are undoubtly useful in run-time,
but not in compile-time? It all boils down to this.

I haven't got the time the actually use MPL during the review.
Based on the paper and the examples -which I looked closely- I vote to
accept the library.
I haven't read the reference documentation, though; only the paper
I'm quite familiar with metaprogramming, so I couldn't see the paper from
the perspective of a brand new user, but from my background I found it very
very good!
