std.format.format should be pure if its arguments have pure 
toString methods or are built-in types. There may be 
implementation issues preventing it for one reason or another (I 
don't know), but if so, then that's a bug that needs to be fixed. 
Regardless, there should be no need for a separate format 
function which is pure.
