Subject: Handling nil values in optional argument
Date: Thu, 11 Jul 2024 22:38:04 +0000	[thread overview]
Message-ID: <q8ObD2xSp-y71FsJI3txjwqQMgV4FX4yyCSiagy0zOSkw-K2od7dpmmVRwJjkrxmvDBBKBdbikv8QNTJB4dJY0Q3lsHqinI3gWB3aI1yo5U=@protonmail.com> (raw)

I have the following tool, but I want that if I pass nil in the third argument,
the function does not assume that fyr was not supplied, but that fyr is actually
to be used as a nil value. 

(defun mundu (monbf funcs labels &optional fyr)

  (unless fyr (setq fyr t))
