Sorry if this is a stupid question, but is there something

just a simple use I am getting compile errors relating to 
`template object.clear`.

When I try:

    import std.array;

    void main(string[] args){
      auto foo = appender!string;
      foo.clear;
    }

I receive the following output:

Is there something I am missing here?

Thanks

I would say that's a bug, because it seems like it's trying to 
get the clear() function used for associative arrays.
