In structured attrs derivations, __json is used to serialize the `env` attribute into a JSON object. If the derivation enables structured attributes AND specify its own `__json`, one of the field will take precedence (the reader can have fun by guessing which one). To reduce underspecification, we disallow `__json` in structured attributes derivations. Fixes #380.
