I've pruned a few blogs from Planet Lisp that were inactive for nearly a year. That means there are openings on the highly competitive Planet Lisp blogging team.

Do you have a blog discussing interesting projects or activities that involve Common Lisp? Can you handle the enormous pressure of a worldwide audience of dozens of Common Lisp-rabid readers? Do you know that digit-char-p may return an integer?

If you said YES! to all those questions, email me a link to your blog, and join Planet Lisp today!

digit-char-p

IIRC digit-char-p was used with the returned integer in one example of "ANSI Common Lisp" (Paul Graham). So, I know the answer if you ask it that way.

I'm not sure if I could have answered the question "Which function can be used to obtain the value of one digit?"

Do you know that digit-char-p may return an integer?

I had forgotten this, but things like this are what I love about Lisp. I never realized how wonderful dynamic typing was until it struck me that in addition to returning a clean "false" or error value from a function, you could also return something useful as "true" (e.g. an integer from digit-char-p).

Dang, you didn't know? Now I gotta think about zapping your blog from Planet Lisp. I got standards to maintain, etc...
