>>1 I do like the idea of being able to move back and forth between the big schemes and having much less implementation-dependent code. Since there is also r7rs.small and any scheme that implements that meets the standard, I don't see it as betrayal. (But then I learned Guile using a book written for Racket and am working on one written for MIT-Scheme)
I am curious to see what comes out of the yellow edition, which the guy in the video described on reddit as "the Yellow Edition featuring SYNTAX WARZ!" - I haven't done enough low-level macros to have strong feelings about it, but I have done enough scheme to know it's something people have strong feelings about. I think that was one of the big things people didn't like about r6rs- being forced to use syntax-case.
I'm doing my part.
