Checking a generic type at runtime

Why does this function need inline and reified?

inline fun <reified T> List<Any>.firstOfType(): T? =
    firstOrNull { it is T } as T?

A.Without reified, T is erased and "is T" is not allowedB.reified makes the function run on a background threadC.inline is required for any generic functionD.reified lets T be a nullable type only
