[plt-scheme] silly question...

The other day I came up with a hack that allows you to use a 
macro-elaboration-time structure instance as a macro. I haven't tried 
it but I bet you could set! the macro field to something else from 
within a syntax-case body, which would have a similar effect to 
set-syntax!.

Look for macro-object.ss on this page:
