Also just did a quick test, and i don't believe this would be possible. It
would remove functionality from the language widely used.
As you are mistaking `iint $var =3D null` params as "nullable". Which they
are not, they are "optional default" parameters. The equals
can be succeeded by any value, to set the parameter to such variable where
the parameter is not passed. `int ?$arg` is not provided as
an alternative, the directive `int ?$arg` simple allows the parameters to
be passed as null, it is still required to pass through the
parameter.
To clarify
`T ?$var` =3D Requires the parameter to be passed to the function, null
value allowed
`T $var =3D null` =3D Does not require the parameter to be passed to the
function, is set to null if not.
