That would kind of defy the whole premise of this thing wouldn't it? The biggest and most sought after "feature" of C is it's speed and direct memory access (and simplicity, I guess).

If you take that away, what's left?

Depends on the application, but I could see some mixture of: 1) familiarity; 2) simplicity; and 3) minimal memory usage. Browsing the source code briefly, it really does look like it's an interpreter, with C structs representing Variables, Expressions, and so on.
