A trailing `.` after an optional node, e.g. `(p (a)+ @a . (b)? @b .)`, sets `is_last_child` on the `(b)?` step. When `(b)?` matched zero, the zero-skip jumped past that step to completion, so the last-child requirement was never enforced. When a zero-skip would bypass a step carrying `is_last_child`, require that the last matched node really is the last named child. Gated on the `alternative_is_skip` edge marker. |

tree-sitter
Tree-sitter is a parser generator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited. Tree-sitter aims to be:
- General enough to parse any programming language
- Fast enough to parse on every keystroke in a text editor
- Robust enough to provide useful results even in the presence of syntax errors
- Dependency-free so that the runtime library (which is written in pure C) can be embedded in any application
