This looks great. Bit confused as to why they seem so reticent to put it in the mainline engine - unless they don’t really consider it fully baked. Does anyone have any insight on this?

I haven’t watched the Simon Peyton Jones presentation yet (wasn’t even aware of it until yesterday) but seeing that he’s involved lends it some serious credibility. I had misunderstood that this was going to be a lightweight scripting language a la GDScript, but I’m now wondering whether they see this long-term as standing shoulder-to-shoulder with C++ in UE.
