Hi,

Consider this generic approach, I think it's better for developers, simpler pattern:

static void Main(string[] args) {
  
    var options = CommandLine.Parser.Default.ParseArguments<Options>(args);

    if (options.Available)
       // Values are available here
       if (options.Verbose) Console.WriteLine("Filename: {0}", options.InputFile);
 
}

just a thought...

Fixed in #634. Example:

var options = CommandLine.Parser.Default.ParseArguments<Options>(args).Value;
if (options != default) {
    // ... do something with your options
}

If you want both the parsed options and the errors, you would do something like this:

var parsed = CommandLine.Parser.Default.ParseArguments<Options>(args);
if (parsed.Value != default) {
    // ... do something with your options
} else {
   // ... do something with Parsed.Errors
}

@Korporal, not sure if you still care, but since you opened this issue initially, I thought I'd tag you that a PR has been created that is similar to your requested syntax
