The experiments you list all extend the run-time syntactic  
environment, not the compile-time environment.  This means that they  
would have the same problem as the one I described with my srfi-8  
example.

Maybe I misread your message where you described Chicken's require- 
for-syntax.  Does Chicken's require-for-syntax extend the syntactic  
environment at run-time, or at compile-time?

I cannot find a description of require-for-syntax in Chicken's  
documentation, but I admit I am not trying very hard to do so.
