I was wondering... Why does `fun String?.orEmpty()...

# stdlib

I was wondering... Why does fun String?.orEmpty(): String was not defined for CharSequence? Is it a multiplatform constraint?

I wouldn't say that's true - many Android APIs take CharSequence, which can be annotated strings

[ephemient]

but it's also pretty easy to write ?: "" so it's not a huge missing gap

Of course, it's something I could define myself, and absolutely minor in the standard library development. But I would think that the inclusion of orEmpty for String alone could justify the equivalent for CharSequence, or at least something like fun <C, R> C?.ifNull(defaultValue: () -> R): R where C : R, for functional programming style.
