You have to pass unlink something to delete. Stat is called
without an argument, hence $_ is used for stat too.
'<' is used to give unlink something to work with. Try it like this:
perl -e 'for(<*>){((stat)[9])>(printf)}'

Files are sorted in directory inode by mtime. That saves you sorting
all the file list in directory.
