error C2672: 'operator __surrogate_func': no matching overloaded function found

I solved the problem :
https://developercommunity.visualstudio.com/content/problem/571058/error-c2672-operator-surrogate-func-no-matching-ov.html

on godbolt it works only with msvc v19.28 and compiler option = /std:c++latest

It looks like a bug, as the intent is to have this work on at least vs2017 without the /std:c++latest option. I'll investigate. Thanks for the report.

Like I understood it just Msvc can't deduce the return value type in this case however in simple case such as auto f() - >decltype (h()) { return h() ;} then he can and another example if I set concrete return type for tag invoke instead of deduction type it works then. Sorry for my English.
