This will be tricky to implement as you've to check if the last statement of the function represents a value or not as Scala does, and a lot of statements in PHP have no values: switch/while/for/if... So function a() { if(true) .. else ..; } would have to implicitely return null, since if() is not a value. > > Thx a lot! > Rune Kaagaard > Denmark > > -- > PHP Internals - PHP Runtime Development Mailing List > To unsubscribe, visit: http://www.php.net/unsub.php > > -- Etienne Kneuss http://www.colder.ch
