giles 317f93b2af ocaml: phase 4 modules + field access (+11 tests, 215 total) ...

module M = struct DECLS end parsed by sub-tokenising the body source
between struct and the matching end (nesting tracked via struct/begin/
sig/end). Field access is a postfix layer above parse-atom, binding
tighter than application: f r.x -> (:app f (:field r "x")).

Eval (:module-def NAME DECLS) builds a dict via ocaml-eval-module
running decls in a sub-env. (:field EXPR NAME) looks up dict fields,
treating (:con NAME) heads as module-name lookups instead of nullary
ctors so M.x works with M as a module.

Phase 4 LOC so far: ~110 lines (well under 2000 budget).
