C programmers are at the end of their wits anyway.

I’d never considered that but it’s an interesting concept. When you’re deciding what to wear you only have half the number of shoes to look at so have a smaller physical area to search and compare. Once you’ve chosen it’s fairly straightforward to find the matching one in the second container.

One downside would be if you have a few very similar pairs of shoes, that would undoubtedly make finding the matching shoe much more difficult because you couldn’t immediately home in on it.

I don’t think I’ll try it, but certainly something new to ponder.
