This kind of issue is the reason why some more modern languages like Rust or Go do not have implicit narrowing conversions. For instance, on Rust, trying to simply pass an usize (Rust's equivalent of size_t) to a function which expects an i32 (Rust's equivalent of int) will not compile; the programmer has to write "size as i32" (Rust's equivalent of "(int) size"), which makes it explicit that it might truncate the value at that point.

(Some Rust developers argue that even "size as i32" should be avoided, and "size.try_into()" should be used instead, since it forces the programmer to treat an overflow explicitly at runtime, instead of silently wrapping.)
