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

silly. There are cases where intersect is great, and where it's kinda
silly.
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
If you can't understand it then you cannot tell what benefit it gives to the
greater PHP community, and if you cannot see that it provides any benefit
then you should vote it DOWN. Common sense should dictate that you only vote
it UP when you are convinced that it will provide something of benefit. If
you don't vote at all you are admitting that you are clueless, or don't
care, in which case you are not preventing a bad idea from being accepted.
If it later turns out that it was a crock of sh*t then you will be partly to
blame because you didn't have the intelligence to see it as such and didn't
speak up. If you don't understand an RFC then not only do you not understand
the benefits that it can provide, you also don't understand the damage that
it can cause.
