Are there any developer experience advantages for `x := 1` over `let x = 1`? A `let` keyword probably improves parsing error behaviour, and makes declarations more visible. := is more concise though.

I travelled recently with six electronic devices, and every single one used USB-C for charging. It was wonderful, and not an experience I've had before.

Today I learnt that A* doesn't work for an arbitrary non-planar graph, you need additional structure: https://stackoverflow.com/q/26568552/509706 This matches my experience with difftastic so far. The graph is non-planar and my best heuristic only matches Dijkstra perf in typical cases.
