Makes it easy to add formatting to any api that is expecting a builder, a strict or lazy text, or a string. It is essentially (flip runFormat), but with a more generous type due to the typeclass.
For example:
>>> formatted TL.putStr ("x is: " % int % "n") 7
x is: 7
>>> formatted T.putStr ("x is: " % int % "n") 7
x is: 7
>>> formatted (id TL.Text) ("x is: " % int % "n") 7
"x is: 7n"
>>> formatted (id T.Text) ("x is: " % int % "n") 7
"x is: 7n"
