-/**
- * @overview
- *
- * The role of the Fluent resolver is to format a translation object to an
- * instance of `FluentType` or an array of instances.
- *
- * Translations can contain references to other messages or variables,
- * conditional logic in form of select expressions, traits which describe their
- * grammatical features, and can use Fluent builtins which make use of the
- * `Intl` formatters to format numbers, dates, lists and more into the
- * bundle's language. See the documentation of the Fluent syntax for more
- * information.
- *
- * In case of errors the resolver will try to salvage as much of the
- * translation as possible. In rare situations where the resolver didn't know
- * how to recover from an error it will return an instance of `FluentNone`.
- *
- * `MessageReference`, `VariantExpression`, `AttributeExpression` and
- * `SelectExpression` resolve to raw Runtime Entries objects and the result of
- * the resolution needs to be passed into `Type` to get their real value.
- * This is useful for composing expressions. Consider:
- *
- * brand-name[nominative]
- *
- * which is a `VariantExpression` with properties `id: MessageReference` and
- * `key: Keyword`. If `MessageReference` was resolved eagerly, it would
- * instantly resolve to the value of the `brand-name` message. Instead, we
- * want to get the message object and look for its `nominative` variant.
- *
- * All other expressions (except for `FunctionReference` which is only used in
- * `CallExpression`) resolve to an instance of `FluentType`. The caller should
- * use the `toString` method to convert the instance to a native value.
- *
- *
- * All functions in this file pass around a special object called `env`.
- * This object stores a set of elements used by all resolve functions:
- *
- * * {FluentBundle} bundle
- * bundle for which the given resolution is happening
- * * {Object} args
- * list of developer provided arguments that can be used
- * * {Array} errors
- * list of errors collected while resolving
- * * {WeakSet} dirty
- * Set of patterns already encountered during this resolution.
- * This is used to prevent cyclic resolutions.
