It's possible (and tested) to slice an arbitrary set of indices off a dimension:

We should improve the test coverage of the various packages. With more reasoning below, the following should have tests:

• Each "class" of generated functions should have (at least) one test (per type).

With code generation, the risk of human blunders ha
