Seems like you look for advanced source-code editors.Some ideas are around for quite a while e.g. here http://en.wikipedia.org/wiki/Intentional_programming I'm not sure if current computer algebra systems also offer a WYSIWYG input mode? Of course this is not clutter and line noise but domain specific standard notation. There has also been a more Python related ambitious multi-language project called Logix that enabled user-defined operators but it seems to be dead.
