The four common number checks we do are:

negative, zero, one, many

In #Ruby, we have…

num = 123

num.negative? #=> false
num.zero? #=> false
num.positive? #=> true

num > 1 #=> true

IMO, it feels like Numeric needs a method for “positive and more than one”

.many? .plural? something like that

I'm always surprised when #Ruby doesn't have an antonym method for a predicate method.

[].empty?
#=> true

![].empty?
#=> false

I know of [].any?
But that's not what I'd expect as an opposite of `empty?`

I understand why #Rails have `.present?` and `.blank?`

Am I missing something in Ruby?
