Agreed that this has some attractiveness to it. What does returning by reference look like in that world though? $fn = function &$lambda($args...) {...}; Capturing lambda by reference doesn't make sense when you've just declared the var, but it looks confusing AF. $fn = function $lambda&($args...) {...}; Hello PERL... > The main question in my mind is whether that means the same variable is > used internally and externally or not. > The prototype I wrote in my brain for this would have $lambda exclusively within the closure's scope, not leaked to the declaring scope. I think I prefer that even though it looks a bit odd to have a name on a function that's not accessible from where it's defined. TL;DR - Still a little confusing. -Sara
