void foo(int delegate(ref int[1]) spam) {}
void main() {
    foo((ref int[1] x) => 0); // OK
    foo(x => 0); // Error
}



DMD 2.062alpha gives:

test.d(4): Error: function test.foo (int delegate(ref int[1u]) spam)(null) is
not callable using argument types (void)
test.d(4): Error: cannot implicitly convert expression (__lambda3) of type int
delegate(int[1u] x) pure nothrow @safe to int delegate(ref int[1u])
