What about adding this overload? ```operator fun &...

# stdlib

[CLOVIS]

What about adding this overload?

operator fun <T> List<T>?.plus(element: T) =
    if (this != null) this + element
    else listOf(element)

I've seen (nullableList ?: emptyList()) + element being used in a few places, and I don't think it's particularly readable (and it adds some useless logic when concatenating the empty list).

You can use nullableList.orEmpty()

[CLOVIS]

Oh, that's good to know. It will still concatenate the empty list with a single element, but it is more readable

This doesn't have the "useless logic" that you mention, but is slightly less readable:

list?.plus(elem) ?: listOf(elem)
