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...
