If by “discovered” you mean “broke”. John, polymorphism entails that it *doesn't matter* whether the object inherits from any particular type; it only matters whether the object behaves correctly. So rather than testing whether the object inherits from ‘unicode’, test whether it behaves how you expect – preferably by just using it as though it does behave that way. -- \ Lucifer: “Just sign the Contract, sir, and the Piano is yours.” | `\ Ray: “Sheesh!
