Interesting the similarities. I do provide more specialized functions for some of those: auto input2 = menu(promptMsg, ["coffee", "tea"]); auto input = require!(string, accept)(promptMsg); I haven't provide the option of displaying an error message, but it could go in the delegate you use in require. And I suppose prompt is a better name than userInput. On thing I've been kind of interested in is getting something set up that would allow providing the needed information via a config, args, or at runtime. but haven't done anything with that idea.
