I'm talking about PHP 5.4. `bindTo` is a Closure method in PHP 5.4, and
allows you to set the `$this` variable inside of a Closure. However,
apparently you can't use it on Closures created inside static methods.
I knew that you could create another function which would return the
Closure, however, that isn't what I asked. I wanted to either use the
`bindTo` method on a static Closure, or create a non-static Closure in a
static method.
