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.
