Don't IDEs highlight variables that aren't read/written to?

  In this case “unused” might mean declaring or initializing a variable and then assigning or reassigning a value to it later. In this case, it is technically used, so most linters won’t pick that up. But it actually does nothing so it’s wasted cycles.

    No decent compiler would waste a cycle on that.
