I'm not keen on StatelessDispatch... because it's a behavior only in
stateless mode.  I think it would be confusing to people who would see it as
a stateless counterpart to StatefulSnippets.  Sorry... I guess I'm a better
critic than I am a doer.  What do others think?  If I'm the only one seeing
a likelihood of confusions, let's go with it.  If there are a couple of
other folks who see a likelihood of confusions, let's try a different name
(not necessarily StatelessBehavior.)
