I am not certain about lego bricks but I think specs, in particular, shows real promise. I think there is still quite a bit of work to be done.
In particular:
- ncollide and presumably nphysics need an overhaul to make them multi-threaded to work with specs better.
- specs probably needs more work such as patterns for inboxes etc?
I wonder if there is a way we can build something like futures/mio but for components?
I also like the idea of an even higher level gfx-rs, hopefully with the option to escape into the lower level stuff when you need it.
