On: Rust for tokenising and parsing

[robertlagrant]

"calling out" is too fuzzy a term to be useful. It covers "mentioning" and "accusing". I wouldn't use it, for that reason.

"unnecessary" is the same. Who defines what's necessary? Is Hacker News necessary?

[kreetx → robertlagrant]

It's definitely necessary: it provides an answer for those who do have knowledge about parsing, read this and wonder why didn't the author do this other often used practice instead.
