Heh, I am slow aren't I.... Anyways, I wasn't trying to bash bash. (It is my 
favorite shell.) I was just trying to suggest that retrofitting a more 
hands-free error handling strategy onto bash might be an interesting idea. Not 
sure how it would work though...

The thing is, the Bourne shell *isn't* a "popular programming language of 
today".  It's from the early 1970s.  Error handling in the shell is just like 
error handling in C, which was developed at the same time by the same people.

And Bash is just the Bourne Again Shell.
