Thank you for the pointer and, more so, your contributions.

That screenshot of SICP in Emacs -- running side-by-side with the built-in Guile interpreter -- induces peculiar sensations. An echo of how things could've been and possibly still are in some obscure(d) corners of the Net. An interactive learning environment that at least points in the right direction. It certainly looks elegant and somewhat inspirational to me (though my inner Alan Kay is voicing some profound objections ;).

In any case: you carried that torch for a while, don't be hesitant accepting apparently undue credit -- there's too little, in any case, to warrant worry. ;)
