Multi-criteria sort with weighted comparators — roadmap #462.

Functions

sortByCriteria<T>(List<T> list, int compare(T a, T b)) → List<T>

Returns a new list with list's elements sorted by compare. The original list is not modified.

thenBy<T>(int primary(T, T), int thenByCompare(T, T)) → int Function(T, T)

Builds a comparator that uses primary and then thenByCompare for ties.
