Maybe I missing something obvious but there seems to no way to do
somehting like this (yes I know the syntex is illegal):

foo<Integer>()

public <T> T foo()
{
     return ack(T this);
}

assume ack returns some instance of T...

How do I pass the type param to to foo?.... everything in the generics
tutorial implies that either it must be defined when the instance is
made and/or T x must be a param:

public Foo<T>
{
  public T foo()
  {
      return ack(this);
  }
}

or

public class Foo
{
     public <T> T foo()
     {
          return ack(this);
     }
}

This would be ok except if foo() is static there is no actual instance
of Foo (it contains nothing but static methods and the default/only
constructor is private).   How do set T at run time (syntatically?)
