benchmark(title, log_level = Logger::DEBUG, use_silence = true) {|| ...}

Log and benchmark the workings of a single block and silence whatever logging that may have happened inside it (unless use_silence is set to false).

The benchmark is only recorded if the current level of the logger matches the log_level, which makes it easy to include benchmarking statements in production software that will remain inexpensive because the benchmark will only be conducted if the log level is low enough.

silence() {|| ...}

Silences the logger for the duration of the block.
