C++ sits on that weird abstraction level where it wants to be a higher level language but it keeps grinding their gears on stuff like pointer sizes, pointer arithmetic or vector sizes and at the same time wants to keep being C compatible and needs that interface with the lower level world

Now compare with how numpy does things: you care about the data size but not the implementation.

Still, I didn't expect less (of a crap fest) from the C++ committee as presented here
