No array type.

[No Name]

There's no way to define the following struct with DEFCSTRUCT:

   struct foo {
      unsigned int bar[12];
      unsigned char baz[6];
    };

The problem is that you can't define fixed-size arrays as a type in CFFI. There's just no way to do it. I don't think it can be done with DEFINE-FOREIGN-TYPE. :pointer would not work here.
