Under an alternative model, the common construct would be something like:
void foo(...) { return switch_(...) { ... } }

That's exactly what Rust does. In fact, you'll find yourself either writing match x { patterns ... } or using monadic programming. A lot, because there is little other choice. Out of interest, what do you think of my free function ternary logic programming: tribool t; if(true_(t)) { /* true */ } else if(false_(t)) { /* false */ } else if(unknown(t)) { /* other state */ } Nobody here seemed to like it. I am looking for something the average programmer will notice immediately and not accidentally assume it's boolen logic going on here.
