Support for commands

Is there any existing way to define commands, intended as classes to execute specific options? IF not, any plan to add support? I would expect something like this, removing lot of the ceremony required to configure the option and run the related logic:

Example:

class CommitCommand : Command<CommitOptions>
{
    public int Execute(CommitOptions options)
    {
        // execute
        return 0;
    }

    // alternative
    public int Execute()
    {
        // access options as property in AsyncCommand base
        var file = this.Options.File;

        // execute
        return 0;
    }
}

class UploadCommand : AsyncCommand<UploadOptions>
{
    public async Task<int> ExecuteAsync(CommitOptions options)
    {
        // execute
        return 0;
    }

    // alternative
    public async Task<int> ExecuteAsync()
    {
        // access options as property in AsyncCommand base
        var file = this.Options.File;

        // execute
        return 0;
    }
}

// Program.cs
var parser = new CommandParser();
var parserResult = parser.Parse(args);
var result = parserResult.ExecuteCommand();

In general I’d like the possibility to discover options and commands through reflection, something similar to ManyConsole.

@ericnewton76 sure, but no support for async 😦 With async main support in C# 7.1, that’s a very important feature.
