[boost] multi_array: num_dimensions() not a static member

Hi,

Shouldn't num_dimensions() be a static member of multi_array as it only 
depends on the size_t template parameter?

I am trying to write some template code that takes a type that models 
the multi_array interface however without an instance of this type I 
cannot determine the number of dimensions of the array.

How should I do this or should a static method be added to the 
multi_array type?

There is a line
BOOST_STATIC_CONSTANT(std::size_t, dimensionality = NumDims);
in the code but this is undocumented.

John.
