Based on the Vim syntax highlighting by Marshall Lochbaum[[0]], with number
parsing from PrismJS highlighter by Christopher Rodriguez[[1]].
The lexed types are selected to be as descriptive as possible while
retaining similar groupings to the Vim highlighter, so the highlighted
code looks familiar to BQN users.
