It really depends on how detailed error recovery you want. Error  
recovery was important in the days when one used punch cards, and it  
might take days to get it run.

Today, when one is working interactively, it is efficient to just fix  
the problems as soon as they appear.

You might want discussing this in the Usenet newsgroup comp.compilers.
