Subject: get nargs for a function
Date: Fri, 28 Aug 2015 09:55:16 -0700 (PDT)	[thread overview]
Message-ID: <9eb51198-614a-49f7-8085-2a068dd28852@googlegroups.com> (raw)

Hi all,

Is there a built in way to return the arg list (actually just the number of args) for a function that has been passed to me?

If I was just in dynamic scope, I could get cadr and count the size, but I have to support closure as well which is caddr (and however that changes in the future).

Best regards,
Sam
