[].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?

@jaredwhite yeah I think in the 00s. The ruby community back then was tiny but full of random interesting initiatives. E.g. I remember the Ruby Package Archive, which would have been a debian-like package system with maintainers instead of a "publish what you want" system like rubygems.Given the recent supply chain attack craze.. well maybe it was an idea worth pursuing.
