This tells me nothing. What value does it add really? Do we need 
yet another way to make a damn string? There is value in having a 
clear, unique interface. I know it's nowhere near unique right 
now but that only more reasons not to add yet another method to 
do what can already be done with 3 (!) more keystrokes.
