TTree containing arrays

Hi,

Is it possible to use TTree to hold and access arrays of basic types 
(i.e. Int_t)?  In particular, I would like to have defined a class which 
has arrays as data members, fill objects of such a class, and save them 
in a tree:

class A {
  ...
  Int_t arr1[10];
  Int_t arr2[10];
  ...
}

a = new A();
t = new TTree("T","test tree");
b = t->Branch("A","A",&a,32000,1);

... then fill the tree ...

I have not been able to get this to work.  In particular this is 
preventing me from being able to use a tree to hold classes like:

class B {
  ...
  TH1S* h1;
  ...
}

Should any of this work, or is support for this planned?  

Thank you,
Glenn
