static code generation p2

[js.mdnq]

Take the example here:

http://forum.dlang.org/thread/vrupqijwqmccdpabmken@forum.dlang.org

note how he provides the body of the method in the mixin. I would 
like to something similar to what he has done but provide the 
body of the mixin after the fact(so to speak).

Something like

class Test {
   mixin make_method!(Test)

}
