There's no "external representation" for environments. In klisp it will just print:
[#environment]
The environment type is encapsulated, so it doesn't give you very useful debug information.
Perhaps having `@` produce an environment is the wrong approach and we should just produce an association list instead - then move `$bindings->environment` into the `?` operative to enable querying.
