depends on the app and how "safe" it is to continue after an error.

google's sawzall, which is a domain specific language used for
analyzing very large data sets, has a run-time flag that ignores all
statements using undefined values (it does keep track of such errors
in a special table that can be examined at the end of the run to see
if the result should be considered acceptable or not).  when you're
computing statistics on a terabyte of data, it's probably safe to drop
a few records due to errors.
