in thread Popping from method that returns a list in one line
You cannot pop the return value of ->get_files because it is not an array.
For an explanation of why this makes a difference, see the FAQ:
perldoc -q "What is the difference between a list and an array"
The Synopsis section of the documentation pop specifies that it requires an array.
