Can someone explain why this compiler doesn't say which procedures or types
are not implemented?  My students, for the 4 years we used Modula-2 on our VAX
had to suffer through this same error message.  Obviously the compiler knows
which symbols weren't implemented.  Why won't it tell us?  Reminds me of a
talk that Dijkstra gave at CMU, in which he said that if a program is not
syntactically correct, the compiler should print just "Not syntactically
correct" as an error message.
