How to handle multiple calls with different returns?

[linkrope]

class Dependency
{
    public int foo() { assert(0); }
}

unittest
{
    auto mocker = new Mocker;
    auto dependency = mocker.mock!Dependency;

    mocker.ordered;
    mocker.expect(dependency.foo).returns(1);
    mocker.expect(dependency.foo).returns(2);
    mocker.replay;
    assert(dependency.foo == 1);
    assert(dependency.foo == 2);
    mocker.verify;
}

throws ExpectationViolationException: Dependency.foo() Expected: 1..1 Actual: 2

BTW:
In the real code, "foo" has a parameter of type Nullable!JSONValue.
So I just rediscovered your Issue 10771 - std.typecons.Nullable throws an exception on comparision of null values.

With ignoreArgs as kind of workaround, I stumbled into the next problem.

It's a bug that your example doesn't work.

About Nullable - looks like it's emulating behavior of null for structs, classes can't be compared when references are null so it's okay. I've updated the issue.

OK

With your fix, I just completed the migration of the first example to dmocks - nice.
