d语言混合类型与串的插件

mixin template templateUGC ( typeStringUTF, string lstrStructureID){
  mixin("public struct "~lstrStructureID ~ q{
      {
        typeStringUTF whatever;
      }
    });
}
mixin templateUGC!(string,  "gudtUGC08");
mixin templateUGC!(dstring, "gudtUGC16");
mixin templateUGC!(wstring, "gudtUGC32");
void main() {
   gudtUGC32 something;
}

注意,如果这样:

mixin template templateUGC ( typeStringUTF, alias AA){
   public struct AA {
      typeStringUTF whatever;
   }
}
//所以其不是`变量的值`.
mixin templateUGC!(string,  "BB");

生成的是AA构,与BB无关.

public struct mixin(lstrStructureID) { ... }//无用
mixin("public struct " ~ lstrStructureId ~ " { ... } ");
//这样

而上面插件是没用的,因为插件的参数,要求是语句.
所以,必须像上面的下面那样插件.
