I don't think Waldyr de Souza wants to alter the behaviour

~~~RUBY
[].any?{} # => false
~~~

so `any?` is not the issue.

Feature #12110: Create a method to avoid vacuous truth?

I often find myself running into unexpected results when using `#all?` for example

```ruby
[].all? { |e| false } # => true
```

Even though it's logically correct could we have a method that express the following?

```ruby
foo.any? && foo.all?(&:bar)
```
