In C++20 they have provided a function std::ssize(container) that 
will return a signed integer type. That way you can write 
templates that assume regular arithmetics and that also will work 
with old containers. Of course, C++ is a language where you need 
to learn idioms to program well… which makes it a challenging 
language to pick up. Smaller languages would be better off with 
breaking changes I think.

(I don't think they have changed the existing containers?)
