Part of the problem here is that what happens if the magic line of code 
call #fix error didn't work. You would just go into a loop. If you can 
fix an error then why dont you do some checks upfront to make sure it is 
going to work in the first place?

In your example you do not need to rescue Error B as the third rescue 
will catch the error and then the program will carry on after the end 
and execute the next available statement.
