WebApr 12, 2024 · I wanted to {}-initialize a vector of unique pointers, but it didn’t work. A std::vector takes an initializer_list by value, so it makes a copy of it. Hence, the compilation will fail if you try to use an initializer_list with move-only types. If you want to use the {}-initializer for a vector, you need to implement the move constructor.

The move has little to do with the behaviour of the example. But the elements of v2 aren't references. They are integers. So, you initialise the non-reference second element of the vector using the value of the first ...
