A "SEL" is simply a C string (char *) that is unique in the runtime.

This was actually just discussed on the Obj-C list. You shouldn't trust that SEL will remain a C String as it isn't a C String in some other runtimes. The type is documented to be opaque so you should use the NSStringFromSelector and NSSelectorFromString functions.
