Catch

[Thomas Lindgren]

More structured exceptions would be nice; add the 
line number where the exception occurred while you're 
at it. 

It would also be generally useful to see the 
actual arguments of the operation that caused the 
exception as well, rather than 'badarg' or 'badmatch' 
or whatever. (For pattern matching, showing the entire
pattern or clause head would be better than just the failing
match.)
