Re: Side effecting constants inside functions

Well, it ran on my interpreter (Hedrick's TOPS-20), and that's roughly
the form I have used in the past.  Out of curiousity, is there any way
to define a form which caches values (computes them once) that is not
self-modifying?  I have more than a casual interest, as this is a problem
we are facing in a language I'm working on.
