not able to compile code when using zip (was able to compile using version 2.3.0)

[nikobarli]

The following code cannot be compiled in v4.0. It was compilable in version 2.3.0. I am not sure if it is intended or not.

auto ZipAndAdd(const rxcpp::observable<int> & in1, const rxcpp::observable<int> & in2) {
    return in1.zip(in2);
}

It gave errors as follows:

rx-observable.hpp(1123): error C2672: 'observable_member': no matching overloaded function found

Removing the const on the second argument declaration fixed this error.

Thanks you for the report!

this is not expected. the major version changes were due to a large change in how the operators were defined.

This should be fairly easy to fix in struct member_overload<zip_tag>. except I cannot see any obvious mistake..
