yeah, but what are they? integers? strings? names without an associated value? how do you create new labels? where are they stored? who keeps track of them?
In this scheme, dispatch tables can be considered to be reverse-lookup namespaces. Where a regular namespace is used to look up a value given its name, a dispatch table is used to look up a name given its value. The switch statement then lets you actually do something based on which name is returned.
