Can I call original function with different arguments?

[mefcorvi]

I tried to do that:

meck:unstick_mod(string),
meck:new(string),
meck:expect(string, strip, fun(String) -> meck:passthrough(["   foo   "]) end),
string:strip("   test  ").

I've expected "foo" as a result but I've got an exception: {{case_clause, {passthrough, [" foo "]}}, [{meck, handle_mock_exception, 4}, ... ]}

As I can see, exception raised because case clause expected what Args in {passthrough, Args} are the same arguments which were been passed to the mocked function:

handle_mock_exception(Mod, Func, Fun, Args) ->
    case Fun() of
        ...
        {passthrough, Args} ->
            % call_original(Args) called from mock function
            Result = apply(original_name(Mod), Func, Args),
            cast(Mod, {add_history, {{Mod, Func, Args}, Result}}),
            Result
    end.

I'm not sure if it is right or wrong behaviour. I suggest replacing Args in that clause to PassthroughArgs or something like this.

Thanks for the bug report!
