Re: Inline switch as alternative to nested inline conditional

Hi Michal I'had the idea similar to your RFC but instead of using switch keyword I think introducing when keyword is better. (as I know a language that uses this keyword is Kotlin) $result = when ($v) { 'foo' => 1, 'bar' => 2, 'x', 'y', 'z' => 3, default => null, }; Above you can see that when syntax is more semantic than switch. And it is easier to implement in parser because it has no statement/expression ambiguity. But this might not be preferred by BC camps because introducing a new keyword might break BC. And if switch is chosen I still think the syntax should be comma separated instead of semicolon separated for consistency with other list expressions (array/function call). $result = switch ($v) { case 'foo' => 1, case 'bar' => 2, case 'x', 'y', 'x' => 3, default => null, }; Cheers On Wed, Oct 16, 2019 at 10:33 AM Michał Brzuchalski < michal.brzuchalski@gmail.com> wrote: > Hi David, > > I'm interested in this feature this is called switch expression and is on > my list of RFC to process after Object Initializer RFC. > > I have an RFC in draft for that and planning to finish it soon together > with some syntax optimisations - you can see it at > > https://wiki.php.net/rfc/switch-expression-and-statement-improvement > > Cheers, > Michał Brzuchalski > > śr., 16 paź 2019, 03:46 użytkownik David Rodrigues <david.proweb@gmail.com > > > napisał: > > > Hello.
