Building with -Wunreachable-code-loop-increment causes a warning due to always returning on the first iteration of the loop that outputs errors on invalid args. Collect all errors, and output them in a single error message after the loop completes, resolving the warning and avoiding popup hell by outputting a seperate message for each error.
