I like `compact` as the basis for the name, but I hope the core team will consider whether the eventual nil-removal method should be called `compacting()`, and whether therefore this method should be called `compactingMap(_:)`. Prior art on the name `compact()` does exist, but I don't think it's strong enough to justify deviating from the API Guidelines.

I don't think we need a full review on this tiny issue; five minutes of the core team's time should more than suffice.
