Can you show us the code that "intern[s] top-level symbols at read
time"? Unless you wrote your own reader, the reader is already
interning the symbols which makes my wonder what you're really
doing. Also, a symbol doesn't need to be interned to have it's
symbol-value set. So, basically, what you're saying doesn't make any
sense. That may be because you're talking about something sensical in
a slightly incorrect way or because what you're doing actually doesn't
make complete sense.
