 Replying to [comment:2 felix]:

 remove the warning.

 Does this warning suggest I shouldn't be using '(declare (safe-globals))'
 or any other optimization where I assert I'm not changing the value of my
 top-level module bindings?

 I understand what is happening behind the scenes to make define-values
 work.  I use it several times in genturfa'i to share a lexical environment
 between two or more top-level definitions, and that means they aren't
 *really* top-level bindings as far as the environment is concerned.

 I really only care about the details when they interact with the
 optimizer, however.  Will you comment on that as it regards this warning
 an any (declare ...) flags I might be using?
