Evolution of Emacs Lisp [pdf]
Elisp is awesome! Emacs is truly an <i>integrated</i> development environment also thanks to this great extension language.<p>This paper provides a nice overview of past and also very recent language developments. For example, support for <i>bignums</i> (Section 7.3) is one of the most exciting new features.<p>Thank you very much for putting this together, and for all your work on Emacs!
