Daily bit(e) of C++ | std::initializer_list
Daily bit(e) of C++ #216, The C++11 proxy object for brace-initialization: std::initializer_list.
The std::initializer_list (C++11) is a simple proxy object around a const-array that is automatically constructed when a braced-initializer-list is:
used as a function argument
used to initialize or assign to an object with an appropriate constructor/assignment operator
bound to auto
Note that we cannot move from a const array, which has performance implications.
