Constant building and throwing away instances… To quote the page: This paper explores how the patterns from the "Gang of Four", or "GOF" book, as it is often called, appear when similar problems are addressed using a dynamic, higher-order, object-oriented programming language. Basically, an Object pool is a container which contains some amount of objects. advanced definition that some OOP languages don’t have.
