The `template<class K, class\... Args, class F>` overloads only participate in overload resolution if `Hash::is_transparent` and `Pred::is_transparent` are valid member typedefs. The library assumes that `Hash` is callable with both `K` and `Key` and that `Pred` is transparent. This enables heterogeneous lookup which avoids the cost of instantiating an instance of the `Key` type.

Inserts an element constructed from `k` and `args` into the table if there is no existing element with key `k` contained within it, and then invokes `f1` with a non-const reference to the newly created element. Otherwise, invokes `f2` with a reference to the equivalent element; such reference is const iff a `*_cvisit` overload is used.

If there is an element with key `k`, then it is updated by assigning `std::forward<M>(obj)`.
