Sure - it only helps for some cases.  It's not possible to do it
in general without implicitly instantiating all combination of
types for these classes.  The bug is that we have Array _and_ Field
at all.  Instead we should have a more modular Array (or Field)
which can optionally provide meshes and relations (and multiple
centerings/materials through custom engines).
