The quote is talking about plain pointers being dangerous. And in turn, the claim above was that some languages have plain pointers that aren't dangerous. Yes, you can put a pointer into an Option that can fail, but that's a different issue. The point is that "can fail" is not built directly into the pointer type, and you can use pointers that don't have that risk. And to be clear, that claim is not directly addressing the issue of SQL null. It's a baseline discussion of what pointers actually imply by nature of being pointers. We can then better build upon that knowledge after we separate "refers to a data location" and "might not have contents" into separate attributes. |
