Abstract
The observer pattern is a popular and necessary pattern, so it is surprising that, unlike other languages (e.g., C#), neither C++ nor the Standard Library come with a ready-to-use implementation. Nonetheless, a safe, properly implemented observer (if there can be such a thing) is a technically sophisticated construct, so in this chapter we’ll investigate it with all its gory details.

Notes
- 1.
C# has explicitly solved this problem twice in successive releases. First, it introduced an attribute called [CallerMemberName] that inserted the name of calling function/property as the string value of a parameter. A second release simply introduced nameof(Foo), which would take the name of a symbol and turn it into a string.
