Increase the number of verbs supported

[unwobbling]

Would it be a possible to remove the limit on the number of verbs supported?

Currently the limit is 16.

Ideal would be no limit if that's not possible due to the implementation 32 would be great.

In:

ParserExtensions
.ParseArguments<>

ParserResultExtensions
.MapResult()

I just searched for this topic at Stackoverflow and unlimited / dynamic number is not possible.

But I would like to have more than 16 parameters, too. 32 would be really nice.

This is already possible. I stumpled upon this while trying to use dependency injection with commandlineparser. I dont think that there is a real limit on the number of verbs by doing it this way:

using CommandLine;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;

var services = new ServiceCollection()
.AddTransient<IController<FooOptions>, FooController>()
// ...
.AddTransient<IController<FooOptions17>, FooController17>()
.BuildServiceProvider();

Type[] optionTypes = [
    typeof(FooOptions),
// ...
    typeof(FooOptions17),
];

Parser.Default.ParseArguments(args, optionTypes)
.MapResult((IOptions o) => {
    Type t = typeof(IController<>).MakeGenericType(o.GetType());
    var controller = services.GetRequiredService(t);
    return t.GetMethod(nameof(IController<IOptions>.Run))?.Invoke(controller, [o]);
},
errs => 1);

The way we managed to get arround the limitation was to get the parserResult.Value as a specific type. This worked because all of our verbs are inherit from the same baseclass.
Examplecode:

ParserResult<object> parserResult = parser.ParseArguments(args, LoadVerbs());

ExampleBaseClass value = parserResult.Value as ExampleBaseClass;
if (value == null)
{
    ErrorCase(parserResult);
}
 result = value.Execute();
