What's your rationale?
Transparency. That is where power comes from. I did the same things with Cells. Reading a slot with the usual Lisp reader method transparently creates a dependency on the variable.

Exposed wiring means more work and agonizing refactoring. kenny -- Cells: http://common-lisp.net/project/cells/ "Have you ever been in a relationship?"
