be honest, I think it's only part of the idea is implemented.

which make it useless.

in PHP, even if you don't return anything, NULL is returned implicitly.

even if a function is declared return nothing(void).

like:

   function a() : void {};

following codes  still works:

   $b =3D a();

so, if you want a void return type, and if you want it to be a useful featu=
re..

above expr should be invalid with an error " a() return nothing"

so, I am -1 on this in complete RFC

thanks
