I expect it is, because it has general recursion. It's not what I'd call a particularly good general purpose language; it's focused on data management (admitedly very important) but mostly neglects every other area of programming languages. No modules, no macros, no generics, no higher-order functions, and the type system is circa-1970.

Actually, the language definition is mostly a lower-bound than an actual description of a language, so I suppose you could argue it either way.

I don't believe so. But it's not an area I'm strong in.
