daysis a method on theNumericclass in Rails, and it creates an instance ofActiveSupport::Durationwithselfpassed to the constructor (this is a bit of a simplification, because it actually calls the class methoddaysonDurationwhich converts the number of days into seconds before creating theDurationinstance).Oh god good ol ActiveSupport. I'm having flashbacks of so many ruby projects trying not to bring it in and basically reinventing it but poorly documented.
I still would say it was the language I've most enjoyed (professionally used most all higher level languages over 20+ years) but it might be nostalgia for a time early 2010s when rails was just freaking magic compared to the ways we used to build web apps.
