Template-ing a 'for' loop in C++?

Question

I have a C++ snippet below with a run-time for loop,

for(int i = 0; i < I; i++)
  for (int j = 0; j < J; j++)
    A( row(i,j), column(i,j)

You could use Boost MPL.

An example of loop unrolling is on this mpl::for_each page.

for_each< range_c >( value_printer() );

It doesn't seem that it's all evaluated at compile time, but it may be a good starting point.
