Delphi used drag and drop and property setting to do most of what you'd do in Rails. Whether it's validation, master-details views, specifying display formats to represent decimal formats as currencies, specify the correct editing control for a database column - all specified as properties on the components representing the connection to the database. You'd then be able to drag and drop columns from the list onto a form, and it would create the correct components depending on type, with appropriate labels, etc. Similarly, drop a grid on a form and get type-aware in-cell editing. Automatic updating of a details view when navigating through a parent data set. Etc. One of the nicest things about Delphi was that you could compile into a single executable that you could deploy without further dependencies. One of selling points of Go, 20 years ago.
