Interesting Listener Behavior...

I just finished my session of tutoring a bright young man in Lisp. We  
meet every two weeks. He's 13, and I want to get him off to a good  
start with programming....

Anyway, he just showed me something I didn't know about Lispworks, and  
it seems like non-standard behavior to me, but it can be convenient...

Try adding a list of numbers like this in the listener:

+ 2 3 4

(No parentheses!! )

Nice finding. That's known for LispWorks. Though I don't use it and  
tend to forget it.

Though, sometimes I miss 'closing-the-last-open-parenthesis-executes'  
that I've used in some other Listener...
