idltype.tk_array is never used. It's there for consistency with TypeCode
kinds and in case a back-end wants to use it.

You can do that, but beware of IDL like this:

  struct S {
    long a, b[10], c[5][6];
  };

There, you have a single type with three declarators, one of which is a
scalar, one a single-dimensional array, and the other a two-dimensional
array.

That kind of IDL is the reason array-ness is part of the declarator and
not the type.

Cheers,

Duncan.
