-- | IRC friendly REPL library.
--   
--   Similar to mueval, but using a server with the GHC API instead of a
--   command-line tool. As a result, it is much faster than mueval.
--   Additionally, repl supports declarations/bindings (and deleting them),
--   type and kind pretty printing, in addition to expression evaluation.

prompt :: Repl [String] -> String -> IO [String]

-- | Enter commands and an expression to a <a>Repl</a>, and immediately

prompt_ :: Repl [String] -> Input -> IO Output

-- | Send input.
send :: Repl a -> Input -> IO ()

-- | Naiively get the next set of results. This <i>does not</i> take into
--   account <tt>patiences</tt>, <tt>patienceForErrors</tt>, or
--   <a>lineLength</a>. However, due to laziness, this may not matter.
