I have also seen switch statements used (abused?) to do a similar thing. Since a switch executes the first statement that is equivalent to the control expression you can pass true as the control expression, e.g.:

  switch(true) {
    cond1: return 1;
    cond2 && cond3: return 10;
Not sure I'd recommend it but it works in a few languages :)

Elixir has cond that does this nicely without resorting to strange switch statements:
