-// This header file defines the `absl::FunctionRef` type for holding a

-// reference is typically most useful as a type-erased argument type for

-// the reference type in this case avoids a copy and an allocation. Best 
-// practices of other non-owning reference-like objects (such as

-// 
-//  An `absl::FunctionRef` is similar in usage to a `std::function` but has the 
-//  following differences: 
-// 
-//  * It doesn't own the underlying object. 
-//  * It doesn't have a null or empty state. 
-//  * It never performs deep copies or allocations. 
-//  * It's much faster and cheaper to construct. 
-//  * It's trivially copyable and destructable. 
-// 
-// Generally, `absl::FunctionRef` should not be used as a return value, data 
-// member, or to initialize a `std::function`. Such usages will often lead to 
-// problematic lifetime issues. Once you convert something to an 
-// `absl::FunctionRef` you cannot make a deep copy later.
