  1. Hi, really nice article! A couple of typos in the code examples. You’re writing log.info instead of log.error when an exception occurs. Cheers!

    1. Thanks for the tip — would you mind pointing out the specific code blocks where the typos occur?

  2. A couple of problems with this principle. High level and low level is vaguely defined. If you apply this to the highest levels, this works fine. But the lower you go, the more this will feel the effects of an extra pointer to resolve or an extra function call. So, make sure that in your language, this results in, as much as possible, zero cost abstractions. Interfaces and Traits are typically fine, but watch out with proxies, abstract classes or any form of wrapper constructs.
