Subject: Re: [PHP-DEV] Callable type
From: hannes.magnusson@gmail.com (Hannes Magnusson)

We have the situation in the docs that parameters declared as arrays
do not follow the typehinting rules, but parameters as class names do.
Re-using the callback from the docs could get confusing when
extensions start to typehint on it, but not the core..

I think there is a subtle difference between a callback, and a callable.
In javascript for example, callback is something that is executed on
certain events "onsuccess" is the typical example.
There is nothing that says the callable parameter gets executed as a
part of an event, and I think the default usecase would be to execute
it right away (f.e. filtering data).

I think I would prefer callable, but I could live with either.
