The bind operation

We accomplish this feat using the Monad's bind operation:

In Haskell, it’s called the bind operation. Other names for bind include flatMap, flatten, andThen, collect, and SelectMany. (That's part of what makes functional programming confusing--different languages use different names for the same thing.) The Lexical Workflow calls it Next.
