Hi internals,

Currently, there are some callables that are accepted by the "callable"
type, but which cannot be used with $callable() syntax. This RFC
proposes
to deprecate support for such "callables":

https://wiki.php.net/rfc/deprecate_partially_supported_callables

It took me some time to understand that this was not a proposal to remove
support for all array/string representation of callables.
This should be made clearer if possible, maybe even list the callable
kinds
which will not be deprecated.

Yeah, I definitely have no intention of deprecating string/array callables
in general. If something works in $callable(), then it's going to continue
working. Added the following note:

Normal "function", "Foo::method", ["Foo", "method"] and [new Foo,
"method"] style callables are unaffected by this change.

Regards,
Nikita

With this, PHP walks another step towards a much needed cleanup.

From me this is a more than welcome change.
