I don't know.
C++ has std::vector and std::string_view, but our slices do these 
two things. It makes things easier sometimes but in the end you 
have to track ownership in your head, especially if you use @nogc 
and -betterC.

Does "dynamic arrays ARE slices" really hurt us?

This change would break a great number of libraries, as said in 
the thread. Personally I have zero interest in more memory safety.

On the other hand, maybe we can go "leap of faith" on this.
It would also help if there was a good std::vector replacement in 
the stdlib, with explicit .capacity.
