Expression

data class Expression(val raw: Any)

Mapbox style expression wrapper: holds a JSON-serializable tree (usually a List with an operator in the first element, or a nested structure) compatible with Mapbox’s expression spec.

Use the factory methods on the companion object for common operators (get, interpolate, match, …). Embed inside StyleValue.Expression for data-driven paint properties.
