Sharing READTABLE macro bindings?

[David McClain]

I just ran into a situation where my own support code had been using the #T reader macro, and then I found another interesting 3rd party package that also uses #T for itself. Naturally, on loading up the 3rd party package, it clobbered my own semantics with its own SET-DISPATCH-MACRO-CHARACTER.

Has anyone created a clever system for sharing reader macros?
