[plt-scheme] %, @, ^, etc.

I believe you put stars around globals to differentiate between them and local variables.

I never believed in putting stars around things though. I never have local variables with real names though, so it's no problem to tell which is which.

But if there are *always* stars, you can just leave them out, can't
you, because they serve no real mnemonic purpose?  *I* don't have an
objection---*you* disagreed with me :-)
