   At one point I thought that the case could be made for putting some sort of exception
handling facility into modula-2.  After going home and mulling over it a bit for a while,
I realized that a "90%" solution could be effected outside of the langauge.   What I'd like to
start seeing now is a consensus on what a good exception handling library should contain; e.g.
    
           exception signalling (call declared exception handlers)
           stack unwinding      (unix style setjmp & longjmp)
           fault inhibiting
           scope of fault handlers
           interaction with processes (i.e. are fault handlers/stack unwinders global or process local).

How about other peoples thoughts on these ?
