Bart,

Thank you for the bug report. Unfortunately, this is an intended
behavior: when a script uses our "exception handler" system[1], the
result on failure is a stack trace. If the stack trace lists "in
function 'try'" then 99% of the time the problem is expected (a socket
timeout or similar).

I would love to have a system that allowed a script to halt (like our
current try-catch does) without generating this stack trace, but I
haven't looked into it deeply.
