I didn't get your message, could you resend?.
I was thinking the same thing, but it seems like a transition step. I'd
rather not keep such backward compatibility hacks (if you will) around
for the long haul. How about a flag (maybe '*') at the start of the
format specification which says "operate in backward compatibility
mode"? We could document it as being only useful for the % to {}
translator, and promise to remove it at some point in the future. Either
actually deprecate it or just promise to deprecate it in the future.
Eric.
