Curious?

Oh !!! I finally get it...

Every time the Lisp reader sees a #:symbol it creates a fresh uninterned symbol item. So unless I explicitly use the print-circle notation, I will end up shooting myself in the foot.

Got it. Thanks for the hints.

To be precise you will run into trouble *if* you rely on printing & reading. When the system expands a macro, for instance, as part of evaluation or compilation it doesn't do that, so it doesn't run into these problems.
