Hake or Garth knows more.
The transition is only done for ArrayDouble and maybe ArrayUInt I guess. For now you should be able to just add: IN_TYPEMAPS_STD_VECTOR_OF_POINTERS(Mesh) in std_vector_typemaps.i where the other similar macros are run. Then you should be able to pass list of Mesh objects to the wrapped C++ method/function. The signature of the C++ function can be any of: bar([const] std::vector< [const] Mesh&> >) where the const are optional (but for now you need at least one of them). We need to reiterate where we want to use the Array<Foo> class. It was primarily introduced to handle std::vector<double>, double* <-> NumPy typemaps. Not std::vector<Foo&> <-> PythonSequence(Foo). But I guess Garth also want's the latter ;).
