Actually, that's why I want that trait :)
But in practice, as your command line programs get a little more
complex, docopt is not enough, you need normal programming with things
like argparse.
So maybe a mix of the two ideas is better, to write most stuff in the
docstring, and then refine its semantics below with normal code.

I am not writing an actual argparsing-library, I thought of starting
one, but then I realized, I don't have the time to do something amazing
like argparse, so I decided to go with a less complex and heavily CTFE'd
version. It looks like that:
struct AppArguments {
string username;
Alias!("username") u;
string password;
Alias!("password") p;
bool credentials;
Alias!("credentials") c;
uint width = 1024;
uint height = 800;
string host;
Alias!("host") h;
ushort port = 25565;
bool no_snoop = false;
}
void main() {
auto args = get_options!AppArguments();
}
I added a default --help function to it, if there is no "help" member
declared in AppArguments, but I realized ... --help without messages is
kinda pointless ...
