Deleting a Folder with Perl SDK

I am looking for assistance deleting a folder with the Perl SDK.  I know the user has privileges.  I think I am making calls to DeleteDatastoreFile_Task incorrectly.

Could someone please point me to an example of using DeleteDatastoreFile_Task or Destroy_Task?  ...or any other way of deleting a folder?

I attempted having the folder mo_ref as del_folderView and calling:

my del_result = del_folderView->DeleteDatastoreFile_Task( name => $del_folderName);

Any assistance would be appreciated.
