// 
// - PipeSource is split. The "take a static input" is one part. The "execute a function and broadcast the result" is another.
// 
// - A FunctionPipe is like PipeMiddle, with the specific purpose of applying an A->B function to each item in the pipeline. Its last ctor parameter is the thing it listens to. (Assume it calls `predecessor.AndNext(this)`)
// 
// - An overloaded FunctionPipe ctor takes a string, to identify it in the ASCII art, when the function is a lambda that doesn't have a friendly name.

// var characterFile = CharacterFile.From(fileName);
var fileNamePipe = StaticInputPipe.Of(fileName);
var characterFile = FunctionPipe.Of(CharacterFile.From, fileNamePipe);

// var configFile = ConfigFile.Matching(characterFile);
var configFile = FunctionPipe.Of(ConfigFile.Matching, characterFile);

// var partialCards = characterFile.ParseCards();
var partialCards = FunctionPipe.Of("CharacterFile.ParseCards", _ => _.ParseCards(), characterFile);

// var localCards = configFile.ParseCards();
var localCards = FunctionPipe.Of("ConfigFile.ParseCards", _ => _.ParseCards(), configFile);

// var localCards = configFile.ParseCards();
var localCards = new FunctionPipe("ConfigFile.ParseCards", _=> _.ParseCards, configFile);

// foreach (var card in partialCards)
var eachPartialCard = new ForeachPipe(partialCards);
