$ perldoc -f fileno

fileno FILEHANDLE
Returns the file descriptor for a filehandle, or
undefined if the filehandle is not open.
...
(Filehandles connected to memory objects via new
features of "open" may return undefined even though
they are open.)

...So I am really wondering if some perlio guru out there could elaborate on that last statement of the perl documentation for fileno(). What, pray tell, is it talking about?

While I am doing my own research, I still appreciate the insight my monkly bretheren may have to offer. Many thanks for the insight.
