This was a very interesting post.  I would like to ask you whether you
think the following description fits the algebra/analysis gap:

(The following is from _Paradigms of Artificial Intelligence
Programming_, by Peter Norvig, discussing two alternate paths to follow
in programming)

(1) Use the most straightforward mapping of the problem description
    directly into [...] code.

(2) Use the most natural notation available to solve the problem, and
    then worry about writing an interpreter for that notation.

The second approach often works nicely in Lisp, which was designed to
be "an *algebraic* list processing language for artificial
intelligence work" (my emphasis, quote from _The History of Lisp_,
McCarthy, 1979).

Christian (and presumably you?) would appear to favour (1).

Regards,
Peter
