On a related tangent, which someone else suggested was relevant here:

Levi Morrison wrote another RFC a while ago on partial function applicat=
ion:

https://wiki.php.net/rfc/partial_function_application

He hasn't had bandwidth to work on it, though.  I have taken a stab at i=
t, and mostly handed it over to Ilija Tovilo who has pushed it further a=
long.  It's not going to be ready for 8.0 by a long shot, but we're hopi=
ng to have it ready for 8.1.  (Exact details to depend on the implementa=
tion, WIP.)

Although it's not the main goal, it would also offer a way to do effecti=
vely the same thing as the direct callable reference RFC:

https://wiki.php.net/rfc/partial_function_application#use_as_an_identifi=
er

It's not an ideal substitute, but it's close to one and wouldn't require=
 a separate syntax.

I mention it here mostly for transparency and to make sure we don't end =
up with multiple competing RFCs that duplicate functionality needlessly.=
