`log` module

A small leveled logger. Four levels (debug, info, warn, error), a current level filter, and a swappable formatter and sink for structured output or redirecting to a file.

import "log" as log;

log.set_level("info");
log.info("server starting");
log.warn("port already in use, falling back");
log.error("could not bind");
