It's going to be really neat to watch what the Julia package ecosystem comes up with now that they have access to truly composable parallelism at the language level. Up until now, most parallelism in the language had to live at the application level rather than being in library code since parallelism either relied on spawning new processes or the Threads.@threads macro which couldn't be nested.
