I read the PhD Thesis of Radul, or, sort of skimmed it. It reminded me a lot of a combination of stream processing functions, popularized by Broy among a lot of others, and visual languages such as LabView and Simulink. It pointed me in the way of how to deal with multicore, at least, on a high level for Hi. It won't be as fast as C, it can never be in the end, but yeah, it'll be cool.
