19 // IMPLEMENTATION NOTE
20 // Though Bind()'s result is meant to be stored in a Callback<> type, it
21 // cannot actually return the exact type without requiring a large amount
22 // of extra template specializations. The problem is that in order to
23 // discern the correct specialization of Callback<>, Bind would need to
24 // unwrap the function signature to determine the signature's arity, and
25 // whether or not it is a method.
26 //
27 // Each unique combination of (arity, function_type, num_prebound) where
28 // function_type is one of {function, method, const_method} would require
29 // one specialization. We eventually have to do a similar number of
30 // specializations anyways in the implementation (see the FunctionTraitsN,
31 // classes). However, it is avoidable in Bind if we return the result
32 // via an indirection like we do below.
