Hi,
as promised in ruby-talk:231855, I'm writing about an interesting blog entry I found, which I had hoped to see here on ruby-talk too:
http://on-ruby.blogspot.com/2007/01/will-rubinius-be-acceptable-lisp.html
It talks about plans to implement a LISP like syntax on top of the Rubinius Ruby interpreter. Interesting questions and answers. Don't be scared by the syntax, instead welcome the possibilities (i.e. macros).
Regards,
Pit
