Over the weekend, I was working with a Matrix Class (courtesy of
  Bob Olson), and it was a pain to initialize a matrix by setting
  each element.  Would it be possible to use a constructor that 
  somehow behaved like the autoinitialization of arrays?

I'm looking for something like:
	Vector :: Vector (float ...)   <-- any number of elems
	Matrix :: Matrix (Vector ...)  <-- any number of vectors
so that I could type
	Matrix fred = ((11, 12, 13), (21, 22, 23), (31, 32, 33));

I realize that this syntax is totally illegal, but could I somehow
  use a similar syntax?  Or could C++ recognize that the extra-parened
  things fit the constructor for a Vector, and that a Matrix takes
  Vector parameters?

GNU mentioned a Matrix library in their upcoming C++ library.  How do
  they do it???
