Thanks Daniel, and I agree an empty subclass of a generic mostly works - but not with GenericArray for some reason. A direct specialisation of GenericArray works fine, but if one creates a subclass as indicated, the C comipler error appears in the compilation of the subclass definition.
I wonder if anyone has suggestions as to why GenericArray should demonstrate this behaviour? Also I note that the doco for GenericArray indicates that it takes a defaulted initial size parameter, but it appears that it just ain't so - giving an initial size causes a compilation error on too many args.
