 # Quote of the Week
 
-> One reason we keep certain things as hard errors rather than lints: it establishes a baseline
-> that you can safely assume about other people's code, since it can't be turned off. And as a
-> result, that baseline can become part of people's mental model of Rust itself, rather than
-> something that might or might not be true in any given codebase.
+> I performed an extremely scientific poll on twitter, and determined this is not how it's pronounced
+>
+> ----
+>
+> Well, it really is Vec<T, A>, pronounced Veck-tah. 😛
 >
-> We have to take care to not use that lightly, because that places work on all users of Rust to
-> maintain code to that baseline. But there are cases where we do. We don't allow using one integer
-> type where another was expected. We don't allow certain operations outside an unsafe block. ...
+> ----
 >
-> I think the standard we should apply is asking whether something is part of the baseline that
-> people should be able to assume about all Rust code, and if that's worth the tradeoff of requiring
-> that baseline of all Rust users.
+> Look, I moved away from Boston to avoid this sort of thing 😄.
