Thank you for making this nice prolog interpreter available for public
consumption. I am trying to port it to MacScheme and other schemes. I will
include this code in the repository as soon as possible.

The construct to "customize" the interpreter is not legal as per
specification for the top-level begin:
   
   (if elk-compatibility (begin
   	(define ...)
   	(define ...)))
   
where the intent is to have these defines become global defines.

MacScheme is also griping about other things in the interval arithmetic
package. More later.
