As alluded to in an earlier email today[1] I am now moving the Union
Types RFC[2] to the discussion phase. The short summary of the RFC is
that it permits a type declaration to be one of several enumerated
types. For example, this is a potential signature for a multi-type map
routine:

     function map(callable $f, Array | Traversable $iterable);
I think what I am missing in the RFC is behaviour with scalar (weak)
typehints, and which type the variable in a class would be converted to.
Take for example:
This is not missing in the RFC; see the section called Weak Scalar
Types in Open Issues. However, it does not propose a solution. I have
been assured by a few people that it is possible and it is just
something that needs worked out.

Should the discussion phase lead to proposed conversion
rules in the RFC for scalar types or is it left for later?
