Hm, not sure, but what about the case of analyzing the components of
bundles in a script? Maybe the bundle itself is a function argument, and
then the function needs to check the sanity of the structure of the
bundle that was passed in?
Point taken. I need to think about that. If it's valid I guess
we should add ismatrix and isbundle? Or, perhaps better, roll
these distinct functions into something we might call typeof?
if typeof(whatever) != "scalar"
