  "textContent": "For block-tailed-expressions like `match`, when they appear in a position that a statement is valid, they are _always_ treated as a statement. This ensures that the parse does not rely on types in the program, which is a very desirable property to keep syntax not interleaved with complicated and turing-complete type resolution.",
