Seems like you look for advanced source-code editors.Some ideas are
around for quite a while e.g. here

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.
