[Haskelldb-users] What about introducing a Connection type declaration?

[Marc W. <mar...@gm...>]

eg mysqlConnect is of type:
mysqlConnect :: MonadIO m => MySQLOptions -> (Database -> m a) -> m a

Typical usage looks like this, doesn't it?


	doSomething :: MonadIO m => (Database -> m a) -> m a -> IO () -- <<
	main=do
		con <- mysqlConnect Options
		doSomething con ..

Wouln't it be mucht clearer to use another typedef to write something like this ?


	newtype CConnection :: MonadIO m => (Database -> m a) -> m a
	doSomething :: CConnection -> IO ()  -- <<  much shorter and clearer
	main=do
		con <- mysqlConnect Options
		doSomething con ..

The first C migt indicate that it's a "connected" connection (parameters have already been applied)..
Or does this already exist?

I'd like to provide a patch if you consider it useful
