Maybe yes, but I am not 100 % sure, as in your example the 
information about the dimension count is lost.

In the numpy example you can see there are 2 columns with 2 rows. 
Your example is an 1 dimension array.

Here I am not sure how the n-dimendions info can be specified in 
a readable way using variadic templates.
