Hi!
It is good there's an RFC. However it seems to lack code examples. I understand it may be obvious to the proposers how it looks like, but it'd be nice to have the actual example there as it is done nearly everywhere else.
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")
You mean an interface/class with that name? The error would be 'expected instanceof callable, string/array/closure recieved.
gettype("strpos") will still return a string, not callable.
A callable wouldn't be fully featured type.
What about default values? Will function foo(callback $cb = 'strpos') { } be valid?
No default values, other then NULL allowed. Otherwise we would need to support array("classname", "methodname") too, and then people would want default array values for array typehinting etc etc etc.
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"?
There is no such method anymore :)
What about ARGINFO? Will internal functions be able to define this type via ARGINFO? How will this be reported in `php --rf function`?
I didn't include arginfo in the patch, but good point. It should probably be included. As Felipe pointed out, ext/reflection hasn't been updated. It should return [ callable $foobar ], just like with any other typehint
