It's not the shebang, it's the -w switch. Take out -w and only use use warnings instead and the error goes away because warnings is lexically scoped but -w is global. Using -w turned warnings on globally which is why your error came from the debugger code as it told you.

I don't know why the action is executed on each line of the loop; I agree that docs indicate that it should be executed only on that line each time through the loop.

Update: Realized the example code had both -w and use warnings.

The way forward always starts with a minimal test.
