You could also try SRFI-48. I have already port it into 
PLT Scheme. The code is now available from Schematics CVS. 
One reason it is not in PLT now is that when doing the 
port, I find several bugs in the reference implementation.
Although these bugs are fixed now, maybe there will be other
bugs. Should I insert the existin code into PLT?
