That is correct.

Oberon-2 added type-bound procedures ("methods" in Simula- and C++-speak) to Oberon. Those did not make it into Oberon-07.

As I recall, Oberon-07 unified REAL and LONGREAL, dropped LOOP ... IF <cond> THEN EXIT; ... END and put RETURN <expr> on the function header instead of making it a statement.  That last enforces "single entry single exit" discipline and allows a function with an apparently-null body, similar to the old FORTRAN statemnt function.
