Well, in this case, I don't believe it's possible to
get the effect of File::EXCL (which basically amounts to
"don't overwrite an existing file") with a string as the open
mode. There are some other combinations of parameters
that are also difficult (impossible) to achieve that way.
(I don't remember exactly what it was, but I think it had to
do with a file that was being opened for reading and writing.
All the strings I tried either wouldn't let me access parts of
an existing file, or otherwise failed to perfrom as I required.)
