Let's talk about any potential application this could have.

The first thing I can think of is that if you're writing a flood-filling algorithm (finding connected components) you should fill with #s instaed of Bs, even if filling with Bs is more conventional. Specially if you're doing competitive programming and need to overkill the optimization process in order to pass the run time.

As for production coding, I can't think of anything. Any ideas?

BTW, this is probably speculation, but it's still worth discussing in my humble opinion.




Things like printing out progress bars for long operations stand out here. Lots of programs have an option to do such as a quick and dirty way to give feedback.
