+# Summary
+
+This is a proposal to add .foreach to iterators.
+
+# Motivation
+
+After a chain of transformations on an iterator it might be desirable to have a side effecting
+operation that consumes the iterator. Adding .foreach to iterators is proposed, which is a common
+idiom in other languages for performing this operation. While the same effect can be achieved with a
+for loop, in general is considered that flat is better than nested and leads to more readable code.
+
+# Detailed design
+
+The design is simple, just syntacting suggar around a loop that consumes the iterator as seen in
+this PR.
