  • While clever, I think you've harmed readability rather than helped it by hiding the return in the block. As a reader, I want the flow control statements to be as explicit and obvious as possible so I don't miss them. That's the reason why PBP makes an exception for them in end-of-line conditionals and loops.

    • This technique is open to abuse, but consider a function with several potential exit points, each of which need to release acquired resources. This technique offers a cleaner approach than a local-goto or cut-and-past resource release blocks.

      • Agreed, to a degree. Carl is trading clarity of control flow for a consistent level of abstraction. As long as the technique is used sparingly and locally, I think it can be a net win.

        But I'll wager that someone will write a Perl6::Critic policy about it in the future, maybe to say that pointy blocks with far-reaching control statements should be simple or not exported beyond the lexical scope.
