note kennethk The issue is that [doc://printf] expects a format string as the first argument (thus the 'f'). When you pass the array reference to <c>Dumper</c>, it returns a single string, which <c>printf</c> interprets as its format string. When you pass <c>Dumper</c> the array, it returns an array of strings and so <c>printf</c> thinks the first argument is the format, and thus only prints that. <!-- Node text goes above.
