However, passing by value is very useful in some situations, so having it on an optional and per-class basis would be fine, I’m sure. For example, it makes very little sense to pass around numbers by-reference. Since PHP lacks by-value semantics, custom user land numerical types have to be immutable, unless you want to do endless copying. With by-value semantics, PHP would do what you actually want here automatically. -- Andrea Faulds http://ajf.me/
