It may be worth noting here that:
1. the "style" parameter also exists for logging.Formatter objects
2. it only applies to the output formatting for output, individual
logging calls are still constrained to using %-formatting by backwards
compatibility issues

(Especially point 2 - I briefly forgot that distinction myself, and I
helped review this feature when Vinay added it)

Cheers,
Nick.
