Fixes

We can argue what is a fix in a language standard and what is not.

Ahead, there are three things that might look like a fix for something that was missing or not working in the previous rules.

New auto Rules For Direct-list-initialisation

Since C++11, there’s been a strange problem where

auto x = { 1 };

is deduced as std::initializer_list<int>. Such behaviour is not intuitive as in most cases you should expect it to work like int x { 1 };.

Brace initialization is the preferred pattern in modern C++, but such exceptions make the feature weaker.

With the new Standard, we can fix this so that it will deduce int. To make this happen, we need to understand two ways of initialization - copy and direct:
