I'm glad you're trying out multi-methods with D:

   https://github.com/jll63/meth.d/tree/experiments

That's some serious code you've written there and you must be happy that 
'virtual' is not a keyword in D. ;)

Maybe others can come up with ideas on a better syntax. Just to get the 
conversation going and without thinking it through, how about something 
like the following?

struct Virtual(Args...) {
     // ...
}

@Virtual("t", "d", "w")
string fight(Character t, Dragon d, Hands w) {
     return "you just killed a dragon with your bare hands. Incredible 
isn't it?";
}

Then, something like the following which would parse the module to do 
its magic:

mixin ProcessMethods();
// Can include 'static this()' for runtime initialization if necessary

Again though, this is just a thought about making the syntax more 
fluent. More for the others to think about it for me. :)
