Convenience shortcut

type Message = String

A Message is represented as a simple String.

class (Show a, Show b, Eq b) => MailboxReader a b where

Main class for readable mailboxes.

The mailbox object a represents zero or more Messages. Each message has a unique identifier b in a format specific to each given mailbox. This identifier may or may not be persistent.

Functions which return a list are encouraged -- but not guaranteed -- to do so lazily.

Implementing classes must provide, at minimum, getAll.
