Not exactly. Perl5 unlink is documented to return the number of files
"successfully deleted". Which may be non-zero even if some file doesn't
exist:
$ touch one; touch two
$ perl -le 'print unlink("one", "two") ? 1 : 0'
1
$ touch one;
$ perl -le 'print unlink("one", "two") ? 1 : 0'
1
No failure signalled …
