What is the correct syntax for initializing an array class member?
I have tried some combinations, all of which have resulted in syntax
errors with the MacIntosh MPW C++ compiler.  If you have an answer,
please e-mail me.  Also, if I happened to miss the answer in some C++ book
or other, could you include the reference and page number?

Here's my example:

class myClass {
  public:
    myClass();  // constructor
    ~myClass(); // destructor
  private:
    Tthing   arrayOfThings[3];  // Tthing's constructor takes an arg...
};

//
//  The following attempt at initializing leads to a compile error...
//
myClass::myClass()
:   arrayOfThings[0](  arg),
    arrayOfThings[1](  arg),
    arrayOfThings[2](  arg)
{}

//
//  This attempt also leads to a compile error...
//
myClass::myClass()
:   arrayOfThings(  Tthing( arg), TThing( arg), Tthing( arg))
{}
