> Can we hide the actual memory layout without big overhead using C++ inline/template functions/classes? Not super easily because the array type needs to know the fields of the class it's containing to do the re-write. This is where you need more substantial codegen to enter the picture. Something like the metaclasses proposal should handle it just fine. Or macros in the meantime.
