Assignment operators

== Synopses

Declared in `<bslstl_pair.h>`

Assign to this `pair` from the specified `rhs` pair, holding the parameterized types `PARAM_1` and `PARAM_2`, and return a reference offering modifiable access to this object. Assign `first` the value in `rhs.first` and `second` the value in `rhs.second`. Attempted use of this assignment operator will not compile unless both `T1` and `T2` supply assignment operators, and `T1` is assignable from `PARAM_1` and `T2` is assignable from `PARAM_2`.

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`.

Assign to this `pair` from the specified `rhs` pair, where the type `rhs` is the pair type native to the compiler's library, holding the parameterized types `PARAM_1` and `PARAM_2`, and return a reference offering modifiable access to this object. Assign `first` the value in `rhs.first` and `second` the value in `rhs.second`. Attempted use of this assignment operator will not compile unless both `T1` and `T2` supply assignment operators, and `T1` is assignable from `PARAM_1` and `T2` is assignable from `PARAM_2`.
