[erlang-questions] I think I wish I could write case Any of whatever -> _ end.

[Robert Virding]

The trouble with this is that _ already has a very specific meaning,
it s the don't care variable. It will always match anything and never
be bound and it is used as a place holder when you know there is
something there but you don't care what it is. Using it in a context
where it gets a value would cause much confusion and lead to funny
inconsistent cases.
