```inline fun lt reified T Enum lt T gt gt List lt String gt toEnums List lt T gt return this map enumValueOf lt T gt it ```

Here is my solution possibly not the most optimal `inline fun lt reified T Enum lt T gt gt List lt String gt toEnums List lt T gt = T class java enumConstants filter it name in this toList `

Here is a full example ` fun main args Array lt String gt val widgets = listOf TOGGLE BUTTON toEnums lt WidgetType gt toSet val expected = setOf WidgetType TOGGLE WidgetType BUTTON assertTrue expected == widgets

Here is my solution (possibly not the most optimal):

inline fun <reified T:Enum<T>> List<String>.toEnums(): List<T> = T::class.java.enumConstants.filter { it.name in this }.toList()

Here is a full example: ` fun main(args: Array<String>) { val widgets = listOf("TOGGLE","BUTTON").toEnums<WidgetType>().toSet() val expected = setOf(WidgetType.TOGGLE, WidgetType.BUTTON) assertTrue { expected == widgets } } '

Just seeing this now. It’s a bit late, but thanks!
