This test is failing because debug() doesn't actually print to the console for some reason. Need to figure out why... Any ideas, @kt3k?

I think you need to call setup and override the default log level to DEBUG like the below:

import * as log from "@std/log";
log.setup({
  handlers: {
    default: new log.ConsoleHandler("DEBUG"),
  },  
  loggers: {
    default: {
      level: "DEBUG",
      handlers: ["default"],
    }   
  }
});
log.debug("debug");

The default log level is set to "INFO" here

Are you suggesting we add that to log/debug.ts? What is the expected behavior of the following script?

import { debug } from "@std/log/debug";

debug("Hello, world!");

I think the expected behavior is noop because the default log level is not low enough to log DEBUG log.
