Moving the decision of "how am I going to be called" to the time of writing the format string is a bit odd.

On the other hand, the specially crafted format string does have the virtue of travelling far more easily through any APIs that wrap the basic format() method (since it doesn't need special treatment to make its way through the wrapping code). Completely agree on all points. Now we're just left with "is it worth expanding the str api for this?". I don't feel strongly either way.

For something as core as the string API, we better feel darn strongly about it before we mess with it :)

I'm inclined to leave it alone unless/until Raymond or somebody else steps up to really champion it.

Cheers, Nick.

P.S. There's also the language moratorium to consider - since this idea affect the methods of a builtin type, I believe the moratorium applies.
