In mathematics-related context, I'd like to define functors working on <cmath> functions. For the purpose of this question, we will be using std::invoke as our functor.
The following code fails as expected, because no overload of get is found. Using std::getwould solve the problem.
Consider the following piece of code:I compiled this program using g++ (Ubuntu 6.5.0-1ubuntu1~16.04) 6.5.0 20181026:
I declare two templates, the first converts the argument x from type T to type U and the second from type U to type T. If I call cast with 10, the compiler does not complain. I think both meet the requirements to be used and therefore there should be...
I realized today that this compiles and runs fine:The two handle methods has the same name, and same number and type (?) of parameters. The only difference is that the second handle method has a stricter generic bound. IDE does not complain at all, and the code compiles fine. At...
Consider this snippet:Live on ColiruIf you run it, you can see that the f(int) overload was preferred, even though std::vector has an std::initializer_list constructor (see #8).

With my compiler (1, 2, 3) work but (4, 5) don't. The compiler complains about its incapability to choose the overload for case 5.
