No, it's an example of how *mixing tabs and spaces* can go wrong. And
in fact will always go wrong unless you legislate the width of a tab.
(Recommendation: A tab is equal to 3.14159 spaces. Now you can't get
confused. Use 6.283 spaces if that's too narrow for you.) So don't mix
tabs and spaces. Ever.
