can create with File::Temp but not unlink

[ybiC]

The following shows my first dabblings into File::Temp, which are essentially pulled directly from it's POD.

The first 2 functions, WERX and WERX2, will successfully create their files in /tmp/.   The second 2 funtions, DUNWERK and DUNWERK2, are supposed to also unlink their created file, but they don't work.

Far as I can tell DUNWERK does not create a file, and DUNWERK2 bombs with the following error:
undefined subroutine &main::unlink0 called at "this_script" line "unlink0..." <STDIN> chunk2.

What am I doing wrong here?
