Thanks to N3797 25.2.11 [alg.equal]/2 "If last1 - first1 != last2 - first2, return false.", we can simplify 23.2.1 [container.requirements.general] Table 96 "Container requirements"
from: "distance(a.begin(), a.end()) == distance(b.begin(), b.end()) && equal(a.begin(), a.end(), b.begin())"
to: "equal(a.begin(), a.end(), b.begin(), b.end())"
This will save 4 lines in an obnoxiously tall row. Related issue: #235
