I guess that would do it :-) As long as I remembered to set -w ...

An exception would be better from my point of view though. I'm doing a lot
of things over DRb; exceptions get nicely forwarded to the client side, but
warnings to stderr stay at the server side and I have to remember to look in
different log files for those.

Also, if I want my code to be warning-free, unit testing doesn't really help
me catch those cases (i.e. even if the code produces the correct answers,
the warning says I should have written |*i| rather than |i| )

Brian.
