> Are there reasons that macros like macroexp-let2* avoid using gensym?

The reason is/was to avoid cons'ing the corresponding strings (I
recommend `print-gensym` and `print-circle` for the rare cases where
you need to look at the macroexpanded code).

Maybe we should have a variant of `print-gensym` which prints the
symbol's address along with the rest?
