Description:
------------
Currently it's not possible to use any constants, variables or anonymous functions in a function parameter as default value. This is for example not possible:

function saveUser($name, $surname, $company = CONSTANT_COMPANY_VALUE) {}

... or even this ...

function calculateGravitationalPull($rotation, $axis, $speed, $grav_const = (3.234 / $rotation * $speed)) {}

I've come across various situations, like the example ones above, where I'd love to be able to inject a configuration value or an anonymous function as a function parameter. 

Coding this all inside the function is of course also possible. However, this would make it much easier to create some specific functions for which we'd be able to say how the function behaves straight from its own function and parameters documentation.
