There’s no need for an interface only file to have a declare(strict_types); declaration since it has no effect on a file with no real code. The nature of exceptions (implements \Throwable versus extends \Exception) falls on the edge of the type hinting issue.
So the question is: How much do we want scalar type hinting (and return type hinting, throwable, iterable) in PSRs? Do we want these things enough to exclude PHP 5 consumers? More to the point, who is our real audience? I don’t think our audience is WordPress (still defining their minimum version as 5.2.5). Is our audience a bunch of green fielders who are pulling in Symfony 4 (which requires 7.1+) ? My hot take is to generally agree with Larry (7.0+ is reasonable where there's a demonstrable benefit, but 7.1 borders on aggressive). I don't quite agree that it's /too/ aggressive, but it should be tempered by some degree of conservatism. Personally, I'd like to hear from project reps. What are your various positions on minimum versions? -Sara -- You received this message because you are subscribed to the Google Groups "PHP Framework Interoperability Group" group.
