FDIS 23.2.1 [container.requirements.general] requires a.size() to have constant complexity.
23.3.5 [list] doesn't specify any exceptions to this.
184.108.40.206 [forwardlist.overview]/2 does: "A forward_list satisfies all of the requirements of a container (Table 96), except that the size() member function is not provided."
This was changed from C++03, which specified that size() "should have constant complexity".
