I note this in Logger.pm:


sub log_message {
  my ($level, @message) = @_;

  # too many die and warn messages out there, don't log the
  # ones that we don't own
  if ($level eq "error" or $level eq "warn") {
    return unless $message[0] =~ /^\S+:/;
  }

  [....]
}

sure enough, if you add a line like
 
   warn "foo: help!"

to an eval test, it appears -- but without the "foo:" prefix, it's invisible.
I'm checking in code to turn this off; this bug should be used as a forum to
discuss this, if it's required.
