Hi!

I can call it in some way. It won't ensure that the signature is compatible with what I expect.

Well, it's like array type - you know it's an array but you can't know if it contains certain element that you expect, for example. As I'm not a big fan of strict typing in PHP anyway, I can't really defend this thing, but this is nothing new - other type restrictions don't guarantee you the code would work properly either, they only guarantee the type.

function foo(callable $cb) { $cb(); } foo("strpos"); // This one in fact is illegal but won't be prevented

But maybe this doesn't matter as type hints purely serve documentation (as E_RECOVERABLE are useless unless we make them Exceptions ...) while

Indeed, E_RECOVERABLE is more or less useless - they are only marginally better than E_ERROR since error handler could be invoked on it. I do not know why people think E_RECOVERABLE makes anything better.
