Yes, given your quotes from Wirth, I agree that Modula-2 opaque types
are much like stt access types. I had remembered the restriction
differently: the type was required to fit in the size of a pointer,
which included integers and enums and small records. Probably the
Modula-2 compiler I used had a nonstandard extension -- or else I am
misremembering.
