Implicit to Explicit: Decoding Ruby's Magical Syntax
summary
Claim: Rails DSL is just Ruby and the talk converts implicit syntax into explicit calls. Demos use binding.pry and Pry shortcuts to inspect self, show-source and docs, and edit models while tests reload; examples include making has_many into explicit self.has_many, explaining method_missing in config, and showing why setters need self.email= vs email=. Live demos execute, introspection reveals receivers and arguments, and tests continue to pass.
