I share some of TFA criticism: syntax highlighting just emphasizes what you should already see without it. The word "return" is a keyword of the language, you don't need it to be visually different from the rest to recognize it. On the other hand, highlighting could help you with semantic. For example rendering in a different color a word that's not been declared/defined before would be greatly valuable. Telling a variable from a type would also be helpful in C-like languages (no, current syntax highlighting schemes don't do this, not even the ones backed by tree-sitter). What about a switch to grey out all local/static definitions and thus emphasize only exported/public ones?
