Perhaps among the best arguments for allowing compilers to at least
sometimes reorder fields is to simply make conceivable someday the use
of C++ adaptations of the clever MI layout algorithms described in
Pugh & Weddell's SIGPLAN '90 conference paper.

For what it's worth, I think that the suggestion that compilers obey
programmer field ordering only inside `extern "C"' sounds fine.
