The title of this post should be changed to "Armed Bear Common Lisp - Common Lisp on the JVM." It's an iconic name, and then people would actually know what the post title was referring to.
That's actually a nice pun with a good explanation, while Armed Bear only raises questions for me. What kind of weapon would you arm a bear with? Why? Aren't bears unassailable enough as it is?
We may thus infer that you would arm bears because of the threat of armed bears. After all, to stop a bad bear with a gun, it takes a good bear with a gun.
