Let's have an
expanded class FOO
  -- empty
end

Any try to print it out, either in a collection (an ARRAY) or stand alone strigger a compile time error such as:

            • Error: Invalid usage of feature `to_pointer' of class ANY. (The target which is of type AUX_EXPANDED40_EXP cannot be converted to a memory address.)

The source lines relevant to this message are the following:

Line 284 column 13 in ANY (/home/paolo/src/liberty-eiffel/src/lib/kernel/any.e):
            to_pointer.append_in(tagged_out_memory)
            ^                                     
Line 421 column 4 in ANY (/home/paolo/src/liberty-eiffel/src/lib/kernel/any.e):
   to_pointer: POINTER
