The use variable does not need to have global scope, and in fact it is probably bad programming to have it so. It can be a local var inside a function that declares a lambda. And the other people are right, using the global keyword inside the function makes it totally NOT a closure cuz a closure is, well, closed, by definition.

This is a lot better than using ‘create_function’ to make anonymous functions. Woot!

These are read-only closures by default. You can make them read-write by using the &-sign in the use() list, but if you’re using a global variable, you just get a normal reference to that variable. In that case, it’s not closure at all. Fortunately, it does work sanely if you define the lambda in a function or method. Then you’ll get a real, private, read-write variable. I hope that’s clear. I’m excited. I can’t use it in paid work yet, but lo! That joyous day is coming.

I’m really curious if these will be ‘abused’ or ‘overused’ or ‘misused’ (by multiple different conflicting defintions!). Having used closures in Groovy where they are very central to the language, I still have a hard time seeing too many use cases in PHP right now. We’ll wait and see how the community adapts to this new aspect of the language!
