le has asked for the wisdom of the Perl Monks concerning the following question:
I'm looking for a module or some other algorithm, that can
generate unique filenames (and maybe returns the filehandle).
I'm currently working on a web app, that writes a file
into a directory.
The problem is, that the filenames should be unique, so if
the script attempts to create two files at the same time the
files don't clobber.
I hope you get what I mean, something like "I need a new file,
and I think the filename 99887766 is ok, but if there's already
99887766, give me 99887767."
