      @wycats @codinghorror @jeffkibuule @tomdale it's all about which coding style you optimize for and which coding style is common.

      @stefanpenner @mraleph @tomdale @rwaldron @codinghorror the idea that only "fixed shape" code is "reasonable" is moralizing.

          @wycats @stefanpenner @tomdale @rwaldron @codinghorror it's a fact that non-fuzzy code is just guaranteed to be faster on any VM.

          @mraleph @stefanpenner @tomdale @rwaldron @codinghorror if you define "non-fuzzy" as asm, true in all VMs, but doesn't imply "should write"

          @wycats @mraleph @stefanpenner @tomdale @rwaldron @codinghorror p sure "non-fuzzy" = mostly static (shapes don't change during runtime)

          @robotlolita @mraleph @stefanpenner @tomdale @rwaldron @codinghorror since object literals are the primitive, nobody writes that code.

          @wycats @mraleph @stefanpenner @tomdale @rwaldron @codinghorror it's more that static is easy to opt in general, dynamic is hard.
