Everything is in the title.

Are filters etc. slower when defined as closures (instead of function definitions)?

@Tobion No, it does not matter how they are defined. Speed will be the same. A function is probably slightly faster as we can optimize the compiled template more than when it is an anonymous function where we need to use `call_user_func`.

This slight difference is what I questioned. On top of that, PHP can also not precompile those `call_user_func` I guess (e.g. when using APC). But it's probably not a big deal.
Since you have many examples in the doc with closures, I hope that it does not become the standard way for people to define custom functions.
