newKeyValueExpression
fun MetadataProvider.newKeyValueExpression(key: Expression, value: Expression, rawNode: Any? = null): KeyValueExpression
Creates a new KeyValueExpression. The MetadataProvider receiver will be used to fill different meta-data using Node.applyMetadata. Calling this extension function outside of Kotlin requires an appropriate MetadataProvider, such as a LanguageFrontend as an additional prepended argument.
