Assign to this `pair` the value of the specified `rhs` pair, holding `first` and `second` values of (template parameter) type `PARAM_1` and `PARAM_2` respectively, and return a reference providing modifiable access to this object. This method requires that `T1` be assignable from `PARAM_1` and `T2` be assignable from `PARAM_2`.
