[petsc-dev] Interesting

    Neat stuff. Thanks for pointing it out.

    I don't think we "need" something this general and powerful for  
current PETSc; though if we were starting to write PETSc today?

    The one place I'd really like to clean up is the double dispatch  
of XXXXView() to get rid of the ugly if () dispatches. But I think  
that is best done using the queryfunction() infrastructure we already  
have, rather than a more general solution. Unless someone has some  
simple, slick alternative.
