No more InputName (and no more “case”)

I had all the best intentions when first created the case command: I would like to “sift” a stream with a clean syntax. But that kind of naturally evolved into two other “support” things: the InputName atom and pattern matching.

Not that these two are inherently bad, but now I feel they don’t really fit into the overall language. They ended up kind of “alien” compared to all the rest.

Also, I’m trying to clean things up the best I can before introducing the OOS (Object Orientation Stuff), so, all that (InputName, case and pattern mathing) are gone, now.
