Ryan Lopopolo(@_lopopolo):You may not like it, but this is what peak performance looks like. This is the "Ruby semantics" layer of Artichoke. A method like `Array#[]=` has a ton of logic in it above jamming the elements into the RArray. Now, all of it is oblivious to the concrete interpreter and this all gets monomorphized away. Differential fuzzing is extremely cheap. This means heap, allocator, the entire VM, GC, object model, backing Hash storage, all of it can be replaced. This was my dream back in 2019 but it is SO tedious to write code like this. Not anymore! Now I can just dream big.
