It’s again a boring day for you and your colleagues at the offices of MegaCorpMoneyMaker, the company you work for. Davina, your colleague developer, seems to be fascinated by a tree you can see through a small window; curious, you ask her what she’s thinking about. “I was considering configuring Tree-sitter for the Best Editor In The Universe™!”, she answers with sudden determination. Wondering what was this Tree-sitter she’s speaking about, but too afraid to show your lack of knowledge, you answer that sitting on a tree has nothing to do with editors, and she should go see a doctor.
