Convert a vector to initializer_list

Question

Everyone creates std::vector from std::initializer_list, but what about the other way around?

eg. if you use a std::initializer_list

Answer 1

Apparently no, it is not possible. There is no such constructor (and I believe for good reasons), std::initializer_list is a weird creature.

What you could do instead is to change someThing() to accept a pair of iterators. In that way you get what you want, provided you can change the signature of that function (it isn't in a third party library, etc).
