I have a vague notion that arc would be a good teaching language ... I wonder if anyone else thinks so.

I think the lack of good debugging support eliminates the current version of Arc as a teaching language. DrScheme is probably a reasonable choice; it's built on MzScheme. http://www.plt-scheme.org/software/drscheme/

Do either of those support CL-style defmacro?

Dr Scheme does. Fire it up, click language then choose language. Pick "pretty big", then (define-macro ...) will do pretty much what you expect. http://www.ccs.neu.edu/home/dorai/t-y-scheme/t-y-scheme-Z-H-...

Side question here, is there a keybinding anywhere in DrScheme to close all open parentheses? It's driving me crazy trying to find it.

Dunno, but the '[' and ']' keys in DrScheme are clever enough to give you '(' and ')' when you need them (and '[' and ']' at other times).

Since discovering this I just keep tapping ']' until the highlighting tells me I'm done.
