I have implemented live reload (in a much simpler and naive way) for my little game engine/framework written in C a few years ago, as a "scene" is essentially a reloadable shared library there. When it worked it was a huge productivity booster and time saver indeed, but I've eventually stopped using this feature that much once I started relying more and more on passing function pointers around as callbacks - so things break pretty bad when the function address changes. I had some ideas on how to tackle that, but never got around to implementing it so far. Language level support looks very neat.
