catch(my_function(A,B,C), 
         my_exception(D), 
        ( writeln(my_exception(D)), 
          fail).

my_function(_,_,C) :- throw(my_exception(C)).

That's all there is to it.

Subject: [SWIPL] Readability of exception handling
 

Hello all,

I am trying to write some exception handling code that is readable but it always looks unnecessarily complicated.  Could someone point me to some code examples of exception handling that are elegant?  All the examples I have come across, apart from the very simplest cases, look like a submission to an obfuscation contest.

Also, is there a reason Prolog textbooks avoid covering exception handling?

Thanks for any suggestions,
Parker
