;; - Maybe accept two juxtaposed non-terminals in the BNF under the condition
;; that the first always ends with a terminal, or that the second always
;; starts with a terminal.
;; - Permit EBNF-style notation.
;; - If the grammar has conflicts, the only way is to make the lexer return
;; different tokens for the different cases. This extra work performed by
;; the lexer can be costly and unnecessary: we perform this extra work every
;; time we find the conflicting token, regardless of whether or not the
;; difference between the various situations is relevant to the current
;; situation. E.g. we may try to determine whether a ";" is a ";-operator"
;; or a ";-separator" in a case where we're skipping over a "begin..end" pair
;; where the difference doesn't matter. For frequently occurring tokens and
;; rarely occurring conflicts, this can be a significant performance problem.
;; We could try and let the lexer return a "set of possible tokens
;; plus a refinement function" and then let parser call the refinement
;; function if needed.
;; - Make it possible to better specify the behavior in the face of
;; syntax errors. IOW provide some control over the choice of precedence
;; levels within the limits of the constraints. E.g. make it possible for
;; the grammar to specify that "begin..end" has lower precedence than
;; "Module..EndModule", so that if a "begin" is missing, scanning from the
;; "end" will stop at "Module" rather than going past it (and similarly,
;; scanning from "Module" should not stop at a spurious "end").
