delete is for hashes, not arrays

Picking nits ... from perldoc -f delete: 

     delete EXPR
             Given an expression that specifies a hash element,
             array element, hash slice, or array slice, deletes
             the specified element(s) from the hash or array.  In
             the case of an array, if the array elements happen
             to be at the end, the size of the array will shrink
             to the highest element that tests true for exists()
             (or 0 if no such element exists).
