There is a mechanical workaround for this.

You first parameterise your classes,
then you use a type/class definition
instantiating the parameters: the latter
construction allows recursive 'and's.

For example, 

class type A' ['B'] ..
class type B' ['A'] ..

type A = B A' and B = A B'

[and similarly for classes, using let instead]
