Inspired by the debugger discussion, I've started implementing QuickType support for the Pike language. You can check it out by cloning my github fork[1], checking out to 'Pike' branch, and following the 'Contribute' section in README.md. After successful installation, you can run $ ./script/quicktype --lang pike test/inputs/json/samples/pokedex.json to see if it's working fine.
The main motivation for this is generate Pike classes for the JSON-RPC messages specified in Microsoft's Debugger Adapter Protocol and Language Server Protocol. I imagine this could also turn out handy for people working with JSON-based APIs.
There is plenty of work to be done here, like supporting enums and handling reserved statements, so I encourage you to contribute! Any feeback is more than appreciated.
