Heime is right:
(defun do-something (arg)
(cond
((eq arg 'this)
(message "yes, this")
(message "did I say this?")
(message "yes, I said"))
((eq arg 'that)
(message "what was that?")
(message "this example gets boring"))
(t
(message "what?"))))
(do-something 'this)
Besides, the doco says that a clause returns its last espression's
value, so it does behave like many little progn.
Cheers
