https://github.com/eclipse/eclipse-collections/eclipse-collections-api: Eclipse Collections is a collections framework for Java. It has JDK-compatible List, Set and Map implementations with a rich API and set of utility classes that work with any JDK compatible Collections, Arrays, Maps or Strings. The iteration protocol was inspired by the Smalltalk collection framework.

A Procedure2 is used by forEachWith() methods and for MapIterate.forEachKeyValue(). In the forEachKeyValue()
case the procedure takes the key as the first argument, and the value as the second.  In the forEachWith() case
the procedure takes the the element of the collection as the first argument, and the specified parameter as the
second argument.
