I tried to use TAG_INVOKE pattern in my project I was implementing myself variant this pattern but it didn't work then I have found your project and I tried to compile example but I got the same error from msvc.

https://godbolt.org/z/jKjxWq - it is your example in godbolt.org , any msvc compiler compiles its with error "error C2672: 'operator __surrogate_func': no matching overloaded function found" but clang and gcc (c++11->17->20) compile well , What is happening , I don't know , What am I doing wrong? What do you think about it ? Thanks.
