serialization library - associative arrays ?

What I'm planning on using is:

static if(
   !is(T == struct) &&
   !is(T == class) &&
   is(typeof(T.keys) KEY == KEY[]) &&
   is(typeof(T.values) VALUE == VALUE[])
)
{
   // static assert( is(T == VALUE[KEY]) );
}

It seems to work, but is rather clumsy.
