This fixes several issues introduced in f1a8455: 1. ReflectionHelper.IsEnumerableType - The implementation had bugs: - type.IsAssignableTo(typeof(IEnumerable<>)) doesn't work for open generics - type.GenericTypeArguments[1] was wrong (arrays have element at index 0) Rewrote to properly handle arrays and generic types. 2. DefaultHelpTextGenerator.ExtractNamesFromEnum - Used wrong variable name (wrappedType2 instead of wrappedEnumerableType). 3. ValueParserProvider.GetParserImpl - Added array type support so app.Option<SomeEnum[]>() works with MultipleValue options. 4. Test expectation - Fixed expected help text format for MultipleValue options (--enumOpt5 <E> not --enumOpt5[:<E>]). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
