Correct. Union types I've always seen presented as offering both

Most of the anti- arguments I've seen for "union types" have fixated
on "int &&
string is meaningless, and Foo || Bar is bad design, so union types
are bad!"
Entirely ignoring the flip side, which is int || string (valid use
cases) and
Foo && Bar (many many valid use cases)
well, that explains why the same person which hase a usecase for a
"scalar" pseudo-type donw-votes https://wiki.php.net/rfc/union_types
but it makes his vote not logical at all
frankly the only valid reasons to down-vote something should be
technical ones which matters for the PHP core itself and not "i don't
understand a feature hence nobody should have it"
You are missing the point. If an RFC is so badly written that someone
does not understand it, or understand what benefits it is supposed to
provide, then there is no point in up-voting it
if i don't undrstand it i don't vote at all - that's the point
not up
not down
