### 982. Wrong complexity for initializer_list assignment in Table 85

Discussion:

According to N2800, the associative container requirements table 85 says that assigning an `initializer_list` to such a container is of constant complexity, which is obviously wrong.

Proposed resolution:

In 24.2.7 [associative.reqmts], Table 85 change:

> Table 85 - Associative container requirements (in addition to container)
> Expression | Return type | Assertion/note pre-/post-condition | Complexity
> --- | --- | --- | ---
> `a = il` | `X&` | `a = X(il); return *this;` | constant Same as `a = X(il)`.
