Possibility of standardized sprintf() in ES4?

I would be very interested in this.  Have a look at our  
implementation (not called sprintf, but has similar goals).  Our  
implementation has an additional goal of keeping an association  
between the result string and the objects it represents.  Being a  
dynamic language, I think es4 should aspire to more than just C sprintf.
