    I don't see what's wrong with the last case. Could somebody explain it,
    please?

In the implementation file, the body of "Put" is syntactically 
illegal:

    PROCEDURE Put(wr: Wr.T; char: CHAR) RAISES {...} = Wr.PutChar;

I wish the above were legal, but the body has to be a 
real body, e.g.

    PROCEDURE Put(wr: Wr.T; char: CHAR) RAISES {...} = 
      BEGIN Wr.PutChar(wr, char) END Put;
