 - **The [cppfront regression tests](https://github.com/hsutter/cppfront/tree/main/regression-tests)** which show dozens of working examples, each with a`.cpp2` file. In the `/test-results/` subdirectory you can see the `.cpp` file that each is translated to. Each filename briefly describes the language features the test demonstrates (e.g., contracts, parameter passing, bounds safety, type-safe `is` queries and `as` casts, initialization safety, and generalized value capture including in function expressions ('lambdas'), postconditions, and string interpolation).
