array access "A[i]" and luabind

Hi,

I try to enable array index in my classes for linear algebra.

At least the calls

  object[ integer key ]
  object[ table key ]

should work. The idea is to make index access as general and convenient 
as possible by providing a syntax like
   Vector[i]
  Matrix[i][j] -- a switch creates a temp. object onto the i-th row if ncols>1
  Matrix[{i,j}] -- a second key type (table) which allows common keys 
for vectors AND matrices
  Vector[{i,0}]
  -- both instantiations, Vector and Matrix, should be of the same data type

Somehow it is not possible to change the __index and __newindex methods 
using luabind. Is there any way to simulate such a behavior or is 
support like this planned?

Thanks
Sebastian
