Ruby iteration primitive isn’t block based, either.

  Of course it is. `for a in b` desugars to `b#each`, not the other way around.

    How do “while” and “until” desugar? Kernel#loop?
    • chrisseaton 12y ago
      Those are two rare exceptions and you're right they don't desugar.
      • picks_at_nits 12y ago
        Those are not “exceptions” to Ruby’s primitives, those are Ruby’s primitives. Things that desugar to methods aren’t primitives. The thing is, they’re rare in practice for cultural reasons.
