Well, really the equivalent Haskell function is 'print', whose type is
'Show a => a -> a'.  'putStrLn' is the equivalent of 'hPutStrLn stdout'.

'show' is intended as the opposite of 'read', where 'write' would be even more
confusing, but it is a pretty awful name (better than JS's 'stringify', though?).

This assumes that the user is thinking in terms of output streams: 'print'
probably means printing a document from a printer to the uninitiated.  I would
personally go with something like 'say'.
