It wasn't mentioned in the docs, but I had a slight inkling that it might be the case that one could have InterfaceTemplates using the same syntax as ClassTemplates (ie class ClassName(T) : [superclass [, interfaces] <classbody>). The following example compiled and ran correctly, outputting "1\n4\n" as expected. Perhaps this warrants a mention in the documentation under Templates, alongside "Class Templates"?



// begin test.d

interface Foo(T)
{
   int aFunction(T anArgument);
}

class Bar(T) : Foo!(T)
{
   int aFunction(T anArgument)
   {
      return anArgument.size;
   }
}

int main(char[][] args)
{
   Bar!(ubyte) one = new Bar!(ubyte);
   Bar!(int) two = new Bar!(int);

   ubyte oneVar = 16;
   int twoVar = 400000;

   printf("%i\n%i\n", one.aFunction(oneVar), two.aFunction(twoVar));

   return 0;
}

// end test.d

Nice.

[btw, and please tell me to shove it if this seems rude, but I'm fascinated at the pronunciation of your name. Any chance you could give me a little phonetic pronunciation? :-) (I'm one of the few residents of Australia that goes crazy when the newsreaders mispronounce "foreign" names; the BBC it ain't!!) ]
