	English Returns:;; A boolean indicating whether or not there is an element with key equal to `k` in the table. Notes:;; The `template<class K>` overload only participates 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. + + In the presence of concurrent insertion operations, the value returned may not accurately reflect the true state of the table right after execution.
