Allow Closures to Declare Interfaces they Implement
This RFC proposes the addition of a syntax that allows closures to declare one or more interfaces they implement. This would provide developers with a more expl...
Structural Typing for Closures
This RFC proposes to introduce structural typing for closures when used with interfaces containing only an __invoke() method. This feature aims to simplify the ...

This is an over-arching description of a multi-step process to add Algebraic Data Types to PHP. That effort is happening over multiple implementation RFCs in o...
Tagged Unions
This RFC expands on the previous Enumerations RFC to allow values to be associated with an enum Case, creating what is typically called a tagged union.
Generator comprehensions
This RFC proposes a new syntax for compact generator creation, or comprehensions as they are known in many other languages. Such a syntax offers a more compact...
