> In LaTeX you can have actual boldface letters, so you should write a boldface letter R to represent the real numbers and so on.

Almost [1] every single student absolutely hates that notation in scripts. Bold is used to draw attention, it should not be abused as being part of the variable/type. Just use the proper symbol.

[1] And I'm only saying "almost" to account for the possibility of there being like 5 super weird people on this planet that think otherwise. I don't know a single person who thinks this is a good idea, even the professors writing their scripts like that think it's stupid and are only doing it due to some nonsense fear of it otherwise not printing correctly due to one single bad experience with a shitty printer in 1950. Or maybe there's some other historical reason for this, but in 2023 I'd classify not using the better notation as malicious.
