  Can you explain the "return at end of sub" thing a bit more? Why would an explicit return have more ops?...

  "return" is a control flow operation, it has to arrange to *leave* the sub from wherever it is. That's additional work compared to just leaving a value on the stack.

  Alright, I'll update the blog post when I get a chance and write another more detailed explanation of the changes.

  Thanks.
