// 
// - 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.
