Hi Stephen,

What's the connection between Map.of()'s randomized encounter order and StableValue 
or the JIT's ability to constant-fold? Are you observing that randomized encounter 
order precludes constant folding? Or are you saying that something should change 
near the (preview) StableValue.map() API? For example, that it should specify a 
particular encounter order, or that its API signature should change?
