	English `hint` is a suggestion to where the element should be inserted. This implementation ignores it. 96/10000 · 96

	English Returns:;; If an insert took place, then the iterator points to the newly inserted element. Otherwise, it points to the element with equivalent key. Throws:;; If an exception is thrown by an operation other than a call to `hasher` the function has no effect. Notes:;; This function is similiar to xref:#unordered_node_map_emplace_hint[emplace_hint], with the difference that no `value_type` is constructed if there is an element with an equivalent key; otherwise, the construction is of the form: + + -- ```c++ 510/10000 · 510

	English Can invalidate iterators, but only if the insert causes the load to be greater than the maximum load. 101/10000 · 101
:1054 :1054

	English The `template<class K, class\... Args>` overload only participates in overload resolution if `Hash::is_transparent` and `Pred::is_transparent` are valid member typedefs and neither `iterator` nor `const_iterator` are implicitly convertible from `K`. 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. 453/10000 · 453
