Here's the pitch deck from Epic. See what you can make of this.
That is a very strange language. It's very Haskell.
The pitch deck is all about execution. 63 slides and they don't even get to data representation. Does this have objects? Structs? Traits? Closures? What?
There's no motivation for how this is is used in games, or why it's a good idea. Now, what they must have in mind is lots of tiny programs, each associated with some game objects. Those have to interact, which is a tough problem. This is supposed to help. But how?
Yet Sweeney signed off on this. It must somehow be good for game programming
