Just like self for a class we can have a keyword like fnself or a variable like $fnself that is automatically available inside the body. For a closure it would be the closure itself while for a function / method it can be even just a little syntactic sugar to functionName(...) / self::methodName(...) (not using polymorphism intentionally). Maybe we decide not to implement this right now for functions/methods but we can at least choose a name that has a wider meaning. As we are talking references, I think there should be a mention in the RFC about how GC will (not?) be impacted? Is the closure reference count incremented just when the Closure execution starts, with no impact on GC? Regards, Alex
