org.eclipse.collections/eclipse-collections/10.0.0 : org/eclipse/collections/impl/utility/ListIterate.java

ListIterate
https://github.com/eclipse/eclipse-collections/eclipse-collections: 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.
