The assumption is that there may be multiple getMethods, and that  
each will return the same resource if you ask for it (otherwise the  
sameAs is a lie). Therefore a robust client will try all the  
getMethods for a thing and all things it is same as, and stop when  
the first one succeeds. If the getMethod for #bar is applied to #purl  
the worse thing that can happen is that it will fail and the original  
getMethod for #purl will eventually be tried and succeed. Smart  
resolvers might use heuristics to choose which methods to try first,  
but this won't change the outcome.
