Defun-type/exec-theory

Collects and returns a special set of runes.

(defun-type/exec-theory names &key (theory '(universal-theory :here)) quiet) searches the theory and collects the :TYPE-PRESCRIPTION, :EXECUTABLE-COUNTERPART, and :INDUCTION runes that were put into the theory by (DEFUN name ... ), for each name in names. Thus, DEFUN-TYPE/EXEC-THEORY is a "constructive" dual of (DIASBLE . names).

The default for the theory argument is (UNIVERSAL-THEORY :HERE). Normally the function will crash if any of the names in names do not have a single rune in the theory. Call with :QUIET T to avoid this behavior. Note however that limitations in ACL2 make it impossible to produce even a warning message if you specify :QUIET T.
