If it's an open filehandle, or a string containing the name of an open
filehandle, defined fileno($foo) will be true.
Otherwise, { not ref($foo) or UNIVERSAL::isa($foo,"IO::File") } will
tell if it is "openable". The former may be disabled under use
strict (as a symbolic filehandle), but I can't recall.
