Anyone ever overridden a builtin by accident?

    Common Lisp solves this problem in a pretty simple way - functions
and variables are in separate namespaces (of course scheme programmers
don't like this very much IIRC) and all global variables are commonly
named *booo* *bah* and etc. so if you are overriding a global variable
you are at least aware of it ...
