The RFC is missing information about what happens in codebases which
already have a "callable" type declared. Will that be prevented or will
they hit a runtime error? ("callable expected, callable type found")

What about default values? Will
    function foo(callback $cb = 'strpos') { }
be valid?

The information on reflection is limited. what shall
Reflection::Parameter::getTypehint() return? Will that method allow to
differ between a class type and this "magic"?

What about ARGINFO? Will internal functions be able to define this type
via ARGINFO? How will this be reported in `php --rf function`?
