Safe switch statements

if the last statement of a case isn't a break, the next case gains the followthrough property, and "and" will be generated as a prefix. Simple.

Also allow commas in case statements for multiple cases.

However, don't break to loops, still break from the switch. Teach people about labels.

switch a
  case 1 or 2 or 3
    doThing()
  case 4
    doOtherThing()
  and case 5
    butStillDoThisOtherThing()

Phase 2 switches

Also allow "boolean" switches

switch
  case test(a)
    doThing(a)
  case test(b)
    doThing(b)
