What a nice piece of code!

I do not have time to dive into it now, but I would like to know how  
difficult would it be to have a Scheme interpreter ?

Is there absolutely no restriction regarding the syntax ? This is a  
nice trick you used. No need of parser...

I really like it. Currently there is no Smalltalk-like debugger for  
Scheme. This might be a good thing to implement...

Cheers,
Alexandre
