Monads

For-comprehensions are a 'simplified' way of writing some specific map, flatMap and filter expressions. There are certain properties of data-structures that make these conversions feasible. Monads are structures that define two operations: flatMap and unit which enjoy properties like Associativity of flatMap and simple Left and Right Unit application. These properties of Monads help simplify for-expressions involving them.
