Hmm, this looks suboptimal for more than one reason. Wouldn't 
`text` benefit from using an appender in its implementation, 
rather than letting every invocation of `to` have its own? I.e. 
there ought to be one Appender per `text` invocation, rather than 
per one `text` argument.

textImpl seems to already have a branch for >1 arguments, but it 
still invokes to!S(arg) for them.
