Right.  My attempt to implement such a strategy is described on the  
ExtendingRequire wiki page.  I came very close to getting it working,  
but in the end I gave up because of cases like this:

(define-syntax foo
   (syntax-rules ()
     ((_) (require-at-expansion-time 'foo))))

(foo)

This is an example of sort of thing referred to by the "Update as of  
June 13, 2006" on the ExtendingRequire page, though a much more  
common example, as stated by the "Update", is the cond-expand form  
from SRFI-0.
