An important part of the concept is to return an iterator to the LHS in scalar context for the laziness an array-ref wouldn't help. And there is no context info which tells me if an X {} is nested or already at the RHS of an assignment. (OK I could use metamagic like Damian's Contextual::Return which I never really understood, I'm still suspicious that it might be a April's fool joke) > you have invented monads. kind of ... already in 2011 ... see YAPC talk (well even earlier if you count in Frankfurt Perl Workshop) > the way to solve problems in purely functional languages OK ... needs disambiguation. I don't really care here about side effects, which is the motivation for monads in Haskell. But solutions which "only" work with code-references and closures (i.e. w/o blessing or other magic) have many benefits ... like portability.
