Er, that is to say, I knew how to use them with a top-level variable, but not that you could omit that and use a sep. expression each time... and I could swear I tried to use expressions that way (apparently you can't do both at once!). :P --[[User:StDoodle|StDoodle (#1059825)]] 02:29, 4 May 2010 (UTC)

Ok, old version no longer needed. A couple cleanup requests:

  • add return
  • change looping to flow control OR add a separate section for continue, break & return
  • the above 3 should each have a lv3 heading

Never mind; the stuff, I fixed it. --StDoodle (#1059825) 19:21, 18 April 2010 (UTC) (Though further info for break, continue & return might be nice).

I was not aware of that use of switch statements, thanks! --StDoodle (#1059825) 13:55, 3 May 2010 (UTC)

  • That use of switch statements was one of the things zarqon and I pushed for when we were cajoling veracity to add it as a mafia feature. It is so much more readable to use a single switch statement than 6 "else if" statements. --Bale 23:33, 3 May 2010 (UTC)

I'm wondering if a more explicit example is necessary. What I'm talking about is:


switch {
case x < 0 && x == x % 2:
   print(x+" is negative and even");
   break;
case x < 0:
   print(x+" is negative and odd");
   break;
case x == 0:
   print("x is zero");
   break;
case x == x % 2 && x < 10:
   print(x+" is a positive one digit even number");
   break;
case x != x % 2
   print(x+" is an odd number");
   break;
default:
   print(x+" is greater than 9");
}

Do you think an example like that would be helpful? --Bale 03:19, 4 May 2010 (UTC)
