I don't understand how it is namespace (it's just named scope for 
me) and why do we need template for that? Probably struct with 
static members would work the same without need for instantiating 
the template.

When talking about namespaces in the C++ sense, the feature of 
namespace is that it can be scattered among many files and can be 
'using'.
