a good library would help developers avoid these issues
there's no reason to call functions without side-effects like vector::contains() without using the return result
most modern compilers support flags like [[nodiscard]] or #[must_use] which emit a warning if a return value is ignored
right now, the move compilers and runtime libraries don't support these attributes which help developers avoid writing incorrect code
nodiscard would be a good feature to add to the compiler and move runtimes

> Yep — the critical bug is in the “v2” updater’s authority check.
> In update_v2 you call vector::contains but you ignore its return value, so the function never enforces that the tx sender is authorized. Anyone who can pass a reference to the shared UpdateAuthority object can update the oracle
