### Relaxing constraints on constexpr functions ### Relaxing constraints on constexpr functions
In C++11, `constexpr` function bodies could only contain a very limited set of syntax, including (but not limited to): `typedef`s, `using`s, and a single `return` statement. In C++14, the set of allowable syntax expands greatly to include the most common syntax such as `if` statements, multiple `return`s, loops, etc. In C++11, `constexpr` function bodies could only contain a very limited set of syntaxes, including (but not limited to): `typedef`s, `using`s, and a single `return` statement.

By default value-captures cannot be modified inside the lambda because the compiler-generated method is marked as `const`. The `mutable` keyword allows modifying captured variables. The keyword is placed after the parameter-list (which must be present even if it is empty).
