> I want that in 2.x, but it needs to be specified in more details:
- [x] **Lines of code**; easy. just count non-empty trimmed lines; separate comment lines from actual lines with executable instructions.
- [ ] **Cyclomatic complexity**; that's probably a job for a parse tree listener. not exactly a walk in the park, I'm not sure how I'd calculate this metric, but it's certainly feasible.
- [ ] **Maintainability index**; even harder, requires the above two metrics, and some "Halstead Volume" fi
