  Make it 16 values and run again :) Sure, the more elements we have, the better hash performs.

  But in case of ints/floats, for instance, for small sets especially, the difference will be even more significant.

  Chained ifs are better than array search (for fixed and known sets of values, of course).

  Exactly - *that* would be very nice :) I believe this is easily doable using templates & mixins, though, not using 'in' operator, but something like InSet!(var, values...).
