Proposed resolution:
Add to pair synopsis:
pair& operator=(const pair& p);
Add before paragraph 9:
pair& operator=(const pair& p);
Requires: T1 and T2 shall satisfy the requirements of CopyAssignable.
Effects: Assigns p.first to first and p.second to second. Returns: *this.
[ 2010-11 Batavia ]
Resolved by adopting n3140.
[ 2010-10-24 Daniel adds: ]
Accepting n3140 would provide a superior resolution, because pair does not depend on the semantic requirements of CopyAssignable.
Addresses US-95
Copy-assignment for pair is defaulted and does not work for pairs with reference members. This is inconsistent with conversion-assignment, which deliberately succeeds even if one or both elements are reference types, just as for tuple. The copy-assignment operator should be consistent with the conversion-assignment operator and with tuple's assignment operators.
