Re: Re: [RFC] Union Types v2

Removing references would be great for implementation 🙂 , but this doesn't look realistic in context of PHP language. HHVM already made steps into this direction with Hack. Thanks.

I personally prefer not to use references at all, but if people do want to use them, we could put a note that references are bad for performance when used with types. People can then choose between: * using types, and not references for good performance. * using references, and not types for good performance. * using references and types, and getting slightly less good performance. > I don't like to complicate the language with features > that shouldn't be often used, Can we start the discussion about deprecating references in PHP 8 then? Very few people are writing code using them currently, and they seem to cause quite a lot of confusion, judging by the bug reports about them. If you're also saying that they are making it difficult to write performant PHP, that seems to be a good argument for looking at what would be needed to be done to remove them. cheers Dan Ack CAUTION: This email originated from outside of the organization.
