Bug description: Reference Native Function in variable (function pointers)
Description:
------------
With the intorduction of closures it would be nice to be able to have some
control over native functions for example:
$foo = function() {
echo 'bar';
}
$foo();
Works fine.
It would be nice to be able to do something like
function foo() {
echo 'bar';
}
$foo = &foo;
$foo();
And ultimately, override the defined function:
function foo() {
echo 'bar';
}
$oldFoo = &foo;
foo = function() use ($oldFoo) {
$oldFoo();
echo 'bar';
}
foo(); // will print 'foobar';
There are several uses for this, just look at the way closures are
commonly used in javascript. It's really useful for debugging, as a
function can be substituted easily.
Though this probably isn't possible due to the clear distinction php makes
between functions and variables.
