  • things to take away: (1) inside a const member function, we can change the value of a member reference or a member pointer! It is the value not the boundness that we can change! (2) capture by copy and capture by reference; there is no capture by pointer; (3) the semantic model of a lambda function, i.e., how it can be translated to a equivalent class. (4) the usage of mutable for a lambda function. (5) avoid dangled references.

TODO

• how is std::function<> implemented.
• A polymorphic class should suppress copying, https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#c67-a-polymorphic-class-should-suppress-copying

• incorrect usage of auto results in slicing.
