As I already said, for me this takes away the whole point of the library,
which is to provide STANDARD result types which people use in their public

If everyone is typedefing their own varieties, this doesn't provide a
standard infrastructure. Sure, it would be useful for people who control all
of their code, but no more than that.

There should be one and only one result<T>, and one and only one outcome<T>,
with those names, which the world should use.

Let's first see if people who favor a narrow interface are satisfied with
value_if, which for me is a very good compromise. Once you have a raw
pointer, things are as narrow as it gets.
