This is wrong implicit conversion bug.

void main()
{
    void f1(int) {}
    void f2(short) {}
    void f3(byte) {}

    // Why these calls are accepted?
    f1(ulong.max);
    f2(ulong.max);
    f3(ulong.max);

    // But, if argument is not constant value, compilation fails.
    ulong x;
    //f1(x);  // is not callable using argument types (ulong)
    //f2(x);  // is not callable using argument types (ulong)
    //f3(x);  // is not callable using argument types (ulong)

    void f4(uint) {}
    void f5(ushort) {}
    void f6(ubyte) {}

    // If parameter type is unsigned, it is collectly rejected
    //f4(ulong.max);  // is not callable using argument types (ulong)
    //f5(ulong.max);  // is not callable using argument types (ulong)
    //f6(ulong.max);  // is not callable using argument types (ulong)
}
