Kettled twice. Extra chewy, extra trustworthy.
Summary
C3, a systems programming language in the C tradition, is moving from unsigned to signed integer types by default for sizes and lengths. The article explains the rationale behind this decision, highlighting bugs and pitfalls caused by unsigned types in systems programming, such as unexpected wraparound behavior, comparison issues, and silent errors. It discusses the tradeoffs between signed and unsigned types, arguing that signed defaults reduce subtle bugs and improve code safety while acknowledging the counterarguments about correctness and domain constraints.

C3 is moving to signed by default, but why are we doing that? Isn't unsigned more correct for sizes at least?
