Thanks @AlexCeleste for the excellent additions! Could you take a look at the comments I left?

By the way -- I think I recall you saying the plan is to incorporate these examples more into the Style Guideline to help flesh it out. Was that right? In this PR or another?

I suppose then it would be quite helpful to use the examples to illustrate the difference between a defect and subset.

I've checked the additions a few times over the past weeks and they look quite good to me overall.

Left a couple of thoughts! Thanks a bunch for sweeping through and addressing comments @AlexCeleste

Missed a comment. Realized we can also use the linking to the standard library for core and other standard library crates as well 🥳

I think we're almost there! Last question about choice of ETF RFC 2119-styling on one section.

Also -- seems as though the double backtick syntax for Guideline title isn't working here:

Could you either remove the backticks or look into how to get this to still render correctly as inline code?

Thanks @AlexCeleste for these excellent examples and fleshing out the style guidelines!
