 r243 // NOTE:
// We don't want to call the method for each component of a variable unitarily, but for all
// its components at once (eg its three components in the case of a vector).
// The unordered_multimap does not do this easily, so the question is whether to:
// - use an ordered_multimap and the algos of std to group the values by key
// - use a map (unique keys) and store as values directly the list of components
