monad-connect (hackage): This library is a basic monadic wrapper over the connection package. It provides a monad transformer which gives your monad stack the ability to maintain a single TCP connection, possibly over TLS and/or SOCKS.  This is very convenient for simple client applications which connect to a single server, but it is not enough for robust applications which want to automatically reconnect on errors. In the latter case, a reconnection and error handling layer can be added on top of the simple transformer provided here.
