Whereas there is nothing you can do about being brainfried, there are
things you can do to help minimize mistakes like this one. The first is
to always attach the line number and filename (and possibly process id)
to any debug messages (or for that matter any log messages) you send.
You can do this yourself like this
print "DEBUG on line", __LINE__, " of file ", __FILE__, ":debug
message\n";
or you can just use the warn function to do your debug printing for you
warn("Debug message");
Make sure not to end the message with a "\n" since that prevents warn
from tacking the line number and file name onto the output.
It may also be important (in the case of log files) to note the version
of the code you are running. To my knowledge there is no standard way
of marking the version of a script, but I have found that a global named
$VERSION is often used for this purpose.
