I doubt it's typical or even genuinely untouched. Maybe he was a tidy-freak, or maybe he tidied it specially before going to the war. But it's surely not a typical person's room. That takes away some of the historical interestingness.
VB used to allow you to omit optional parameters by just leaving it blank
foo(36,,,54)
sure it won't do if there are dozens but for the odd ugly case where you naughtily use optional parameters it's OK.
It sounds like there's a need for IDEs to show the parameter names all the time. They could just be inserted automatically into the display if you want to see them, or turn them off if you don't like that. Better than being always on like this proposal.
This might sound negative, but I'm really curious why this is needed if you have an IDE that tells your the parameter names as you're typing and in a mouseover. If you need it to be more visible, make that a feature in the IDE to show you the parameter names all the time. Why change the language?
Not only that, but why are you passing so many parameters like top, bottom, left, right? At least put them in a struct if you can't make them fields of the object itself.
This feature seems like "too little, too late". Maybe 30 years about it would have been helpful.
