Hi! Explicit type parameters KEEP is available for discussion.
TL;DR: explicit function type parameters require explicit arguments provided on each call site:

inline fun <explicit reified T> List<*>.castAll(): List<T>

val list: List<CharSequence> = listOf("a", "b", "c")
val ok = list.castAll<String>() // ok
val error: List<String> = list.castAll() // error: type argument required
