Two new features has been incorporated into 5.8.0rc2 which allow for the creation and handling of temporary files in a secure manner. The first is the incorporation of means to create anonymous temporary files, similar to the unlinking of open files described above, without the need to make use of external modules via:

open( $fh, '+>', undef ) || die $!;

Where the undefined value is a literal undef statement, rather than an undefined variable. It should also be noted that the File::Temp module has now too been incorporated into the core distribution.

Another feature which allows for temporary file-type handling within code is that which allows for file handles to be opened into a memory space, via a scalar reference - For example:

open( $fh, '>', \$variable ) || die $!;

    [shmem]: same with undef as last element
    [msh210]: oh, good point. It's the best kind of correct
    [shmem]: msh210: but I'd not call it a lie outright. That's when you do know the truth.
    [msh210]: I don't have sendmail (I'm on MS Windows), so does one of you think you can report the bug?
    [shmem]: msh210: 'tis about time to tell the sad truth to perl5porters - via perlbug
    [msh210]: probably whoever wrote that actually knows the truth
    [shmem]: msh210: you can save the perlbug text in a file and send that via your mail agent of choice
    [msh210]: hm, okay, I'll try, thanks
    [shmem]: ...not as an attachment, it's probably better to c&p that into the mail body
