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,
Micha=C5=82 Brzuchalski
