// A check that detects const local variable declarations that are copy
20
// initialized with the const reference of a function call or the const
21
// reference of a method call whose object is guaranteed to outlive the
22
// variable's scope and suggests to use a const reference.

// The check currently only understands a subset of variables that are
25
// guaranteed to outlive the const reference returned, namely: const variables,
26
// const references, and const pointers to const.
