    When I had a loaner MacIvory a couple of years ago the release notes
    mentioned some optional "block compilation" facilities that were
    included in Genera 7.3 Ivory as an experimental facility.  I don't know
    whether they were Ivory-specific or not, but I don't recall anything
    about this in the 8.0 release notes.  This stuff might have included
    tail recursion and tail call optimization.

You are probably thinking of the special Ivory instructions for doing
block memory access.  These are described in the Internals book in the
Ivory-Only Subprimitives section.  They aren't experimental.
