|Subject:||Re: [Chicken-users] testing if a symbol has been interned|
|Date:||Fri, 19 Dec 2014 22:40:37 -0800|
In Common Lisp, clisp specifically, you can test whether a symbol has been bound, that is interned, or not using boundp; is there a way to do this in Chicken?
(boundp 'a) ; nil
(defvar a 1)
(boundp 'a) ; t
I wrote up a function once a while back that used exception handling to check if a symbol had been defined, but if there's already an egg that provides this support or if it's built-in, I wanted to know so that I wouldn't have to bother trying to rewrite said function.
