Go has an elegant approach to defining example functions, which are shown in docs as `main()` with the output:

TIL Rust has an ambiguity `if Foo {}` -- is `Foo` a value of type bool, or a struct? Rust solves this by defining a grammar production 'any expression except struct literals' and using it in this position.

Are there any good tools for generating boilerplate code? If I'm a web framework author, I'd love to provide a *discoverable* tool for defining a new controller. This is especially important if files need specific naming conventions or to be in certain directories.
