seqfans,

these are the very problems that i was working on all through the 80's
when i wrote my prototype "theme one" program, in the general context
of indexing 2-level formal languages, of which (finite fragments of)
integer sequences are a special case.  the "test of concept" is
primitive in a way by today's standards but implements a few
data structures that are yet to be as widely applied as
they might.  i started trying to document these ideas
in a generically re-usable way at my "inquiry" site:

http://stderr.org/pipermail/inquiry/
http://stderr.org/cgi-bin/mailman/listinfo/inquiry

here are the anchors of some pertinent threads:

http://stderr.org/pipermail/inquiry/2003-March/000100.html -- exposition
http://stderr.org/pipermail/inquiry/2003-March/000115.html -- source code
http://stderr.org/pipermail/inquiry/2003-March/000120.html -- commentary
http://stderr.org/pipermail/inquiry/2003-March/000141.html -- motivation

it may be another year or so before i can finish (or even get back to)
the te deums of documentality, but if anybody is remotely tantalized
i will do my level best to explain what's going on there.
