Intent

Monad pattern based on monad from linear algebra represents the way of chaining operations together step by step. Binding functions can be described as passing one's output to another's input basing on the 'same type' contract.

Applicability

Use the Monad in any of the following situations

• when you want to chain operations easily
• when you want to apply each function regardless of the result of any of them
