On #emacs today:

solaries: is it still advantageous to learn elisp? I tried to do it, but if you always compare it to Python you don’t find much incentive…
sachac: solaries: Incentive: you can’t program Emacs in Python. ;)
resolve: , pymacs
fsbot: resolve, PyMacs is at http://www.emacswiki.org/cgi-bin/wiki.pl?PyMacs
resolve: but yeah, learn lisp, it’s fun :-)

I should stop making statements like that. “You can’t program Emacs in Python.” is like “You can’t play Tetris in Emacs.” Chances are, someone’s implemented the most obscure or outlandish of features… ;)
