Storing auto types in classes

[Rob Adelberg]

I'm sure this has come up before, but I want to store something like an
std.array appender in a class.  All of the examples use auto for the type but
you can't put that in a class definition, so what do you put?

Example:
class packet{...}

class A {

   packet []  packetlist;
   appender!(packet) packappender;   // wrong format

   this () {
  packetlist = new packet[0];
  packappender = appender(packetlist);
   }
   :
}

What's the format to store the appender in the class?

In this case, the type would be Appender!(packet[]). However, if you ever want 
to know the exact type of something, one way to do it is something like this:

writeln(typeid(appender(packelist)));

It will print out the type of the expression for you.
