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. -- Alexej Magura |
