adds names to current theory
Major Section:  THEORIES

(enable fact (fact) associativity-of-app)

General Form:
(enable name1 name2 ... namek)
where each namei is a runic designator; see theories. The result is the theory that contains all the names in the current theory plus those listed. Note that this is merely a function that returns a theory. The result is generally a very long list of runes and you will probably regret printing it.

The standard way to ``enable'' a fixed set of names, is as follows; see hints and see in-theory.

:in-theory (enable name1 name2 ... namek)  ; in a hint
(in-theory (enable name1 name2 ... namek)) ; as an event
(local ; often desirable, to avoid exporting from the current context
 (in-theory (enable name1 name2 ... namek)))
Note that all the names are implicitly quoted. If you wish to enable a computed list of names, lst, use the theory expression (union-theories (current-theory :here) lst).
