Re: More questions about exported symbols and general style.

Well, two questions about exporting symbols, really. Say I want to set
up bindings to captured variables (like IT in anaphoric macros) in
packages that I'll be using. Do I want to just export IT and friends,
or should I walk through the code and replace them with gensyms or
something?

This is a bit of a tangent, but: don't write anaphoric macros. Making
names magically spring into existence without visible bindings is not
very Lispy.

When bindings are explicit, you don't have to worry about exporting
IT; the user can just use a symbol of their choosing. Plus, it nests
properly.
