And just in case anyone actually tried this, it won't work.  The  
reason is that I'm doing (essentially) this:

(defconstant +guardian+ (gensym))

as part of my iterators code.  But it turns out this is a broken idiom  
because, as Gary points out in http://trac.clozure.com/ccl/ticket/539:

The spec says:

"If a defconstant form appears as a top level form, the compiler must  
recognize that name names a constant variable. An implementation may  
choose to evaluate the value-form at compile time, load time, or both.  
Therefore, users must ensure that the initial-value can be evaluated  
at compile time (regardless of whether or not references to name  
appear in the file) and that it always evaluates to the same value."


I am open to suggestions on how to fix this because this leave me at a  
bit of a loss.
