Conveying meaning at the bitwise operator level is a different thing than applying emphasis to a few words in a sentence with bolding or embedding a hyperlink in a document.

I’ve frequently seen mistakes in Markdown syntax that lead to content that has at best partially-broken formatting, at worst losing some of the content, sometimes even in ways that aren’t obvious.

Markup versus computer code is of course not exactly the same, but the nature of the mistakes—tokens in places they’re not supposed to be, and such—would generally lead to a syntax error in C++.
