Ruby has syntax sugar, no need to remove the funny parts.
Lisp has completely different runtime semantics. Even the lexical scope in Ruby is extremely peculiar. One of the hard parts of writing this document was to remove the intuitive influence of Lisp because it just doesn't make sense for Ruby.
For example, SmallTalk is a class based OO system, yet this postcard doesn’t slow you how to create a class.
OTOH Ruby doesn't need a postcard, it needs a full poster.

This is just an intermediate representation, it's not meant to be used directly (even though you can do that, of course).
