The problem is that in order to +// discern the correct specialization of Callback<>, Bind would need to +// unwrap the function signature to determine the signature's arity, and +// whether or not it is a method. +// +// Each unique combination of (arity, function_type, num_prebound) where +// function_type is one of {function, method, const_method} would require +// one specialization. We eventually have to do a similar number of +// specializations anyways in the implementation (see the FunctionTraitsN, +// classes).
