I meant copies and moves in general. And I'm saying there aren't a lot beyond those, but they exist. Take for example a union of associative containers: one must verify whether the element being inserted is already present in the container with the same key. This means the insertions may need to have different code for inserting each element in case the *comparison* throws, even if the element copy/move is noexcept. -- Thiago Macieira - thiago.macieira (AT) intel.com Principal Engineer - Intel DCAI Platform & System Engineering
