Why does toString() exist? It seems useless.

I strongly favor library solutions over language solutions for this. 
Even if there were a language solution, I would still want a library 
solution so I could better enforce separation of concerns. Unless I want 
to use dependency injection on my domain classes, which is an 
Abomination unto Nuggan, or put complex formatting logic into them, 
which is nearly as abhorrent.
