Hi, good notion to check all the HAVE flags. - I think Bluez is a GPL project and that's probably the explanation (all GPL code was purged) - Now that...

This is more or less covered by [astar](https://docs.rs/petgraph/0.4.7/petgraph/algo/fn.astar.html) now #143; you can always use it with the trivial heuristic (returning 0).

Just punting this to external tools seems fair enough to me. I can see how none of the suggestions really work out, except for indentation.

Good idea there too: maybe a type parameter for element and dimension is better than associated types. Best to try both..

Logically they are associated types: A specific type like `Array` has an assoc. type for the element (`f32`) because it is given from the type uniquely.

Here are some tantalizing examples of what `impl NdArray` can look like. This kind of interface looks very flexible! Instead of dynamic typing, we get abstract types, and we can...

draft. Doesn't look good in github, fine in vim, fine in rustdoc's fonts. ```rust array![0, 1, 2] + array![1] shape [3] + shape [1] = shape [3] ┌───┬───┬───┐ ┌───┐┄┄┄┬┄┄┄╮ ┌───┬───┬───┐...

yes, ndarray does not implement the third case.

As you know arrays in ndarray have dimensionality in the type. If we add `Array + Array` the result needs to be a `Array` where `D3` is some sort of...
