require "logger"

log = Logger.new(STDOUT, level = Logger::WARN, formatter = Logger::DEFAULT_FORMATTER, progname = "")

I actually have wanted to redesign Logger for a while to cover usecases of library logging. For example, a library should just be able to create a logger and log whatever it wants in whatever detail it wants, then there's a centralized place for the application to configure logging level and formatter per-library and globally to define what's seen. Somewhat like the java logging frameworks but not so... bloated.

Sounds bloated, yeah (and an idea for an experimentation shard), and has nothing to do with configuring the logger with kwargs, in addition to getters/setters.
