data-structure secrecy

[Eric Dean Tribble <tribble>]

To those of you not steeped in the enfilade and ent mysteries, I just
wanted to mention how extremely proprietary they are.  Various opaque
pieces of the algorithms float by on this list without much
explanation of how they all fit together, but an inadvertent word (that
there is some connection between enfilades and trees, for example)
could let others produce something akin to many of the enfilade
types (this won't help them with the ent, but even so...).

Thanks,
dean
