null literal requires an explicit cast, in order to be considered a match for a
parameter of nullable type.

----
class C
{
}

void foo(T)(T x, C c) // C - a nullable type
{
}

void main()
{
    foo(1, null); // fails
    foo(1, cast(C)null); // ok
}
----
test.d(17): template Test.foo(T) does not match any function template
declaration
