As alluded to in an earlier email today[1] I am now moving the
Nullable Types RFC[2] to the discussion phase. In a nutshell this RFC
proposes syntax for declaring a type to alternatively be null.
There is a decision that needs to be made: does the question mark go
before or after the type name?
function (?Foo $foo);
function (Foo? $foo);
There are precedents in several languages for each position. Some
relevant issues to where the question mark goes are noted in the
RFC[3].
I look forward to a helpful and meaningful discussion!
