I have no idea what they are doing in their implementation, there are of course
trade offs. When we decide to globally break the ABI to implement a C++11
Standard Conforming std:list we mean to add a data member to provide an O(1)
list<>::size(), that is what we already "experimented" in 4.7.0. Unless of
course over the next months somebody suggests something else which goes well
together with our other design choices.
