-A common pattern in PHP is iterating through a list of objects and executing certain methods of the function. This is especially common when it comes to 1:n-relations (e.g. one object, n adapters).

This is especially common when it comes to 1:n-relations (e.g. one object, n adapters). This proposal is meant to abstract those iterations in convenient functional constructs by adding method call iterators and iterator functions.
