;; Notes:

;; This assumes that the `sed-fix-defs' sed script has been run over all
;; input files (to convert schemey things to their lispy equivalents)

;; Todo:
;;  * doesn't check for `listable' type-property
;;  * guile-gtk `struct' and `ptype' types
;;  * not possible to wrap functions returning vector types

;; WARNING: This makes some pretty gruesome assumptions. [where?]
