When compiling `if`, the compiler assumes that `0` and `1` are the only possible values; there is no saying what could go wrong when that assumption is violated. (This is a compiler-understood *validity invariant* that is fixed in the language specification, which is very different from a user-defined *safety invariant*. -See [this earlier post]({% post_url 2018-08-22-two-kinds-of-invariants.md %}) for more details on that distinction.) +See [this earlier post]({% post_url 2018-08-22-two-kinds-of-invariants %}) for more details on that distinction.) What is less obvious is why calling `example` on `3` is UB even when there is no such `if` being executed. To understand why that is important, let us consider the following example: -- 2.30.2
