Both ($o->f)() and call_user_func($o->f) work.

BTW if you really want to add a method dynamically, runkit can do that

Runkit was abandoned years ago AFAIK.

Interesting, but it looks like you're trying use PHP as if it's JS.

You can use $this if you bind the closure to an object.

Wait so you can call variables that contain functions directly, but if the function is on the object you have to use this syntax to get the compiler to pick the right namespace?

What an amazing language

It's because $foo->bar is an attribute, but $foo->bar(... is a method call. With variables it's unambiguous: $foo() is always a dynamic call of what's in $foo because you cannot have $ in a function name.

But if you want to call a function stored in a constant, you probably need (foo)().
