AEL switch & case

Hi.

I think I've discovered a bug in either the implementation of the 
documentation of the AEL switch command.

https://wiki.asterisk.org/wiki/display/AST/AEL+Conditionals gives an example 
of using switch, and states at the bottom:

"Neither the switch nor case values are wrapped in $[ ]; they can be 
constants, or ${var} type references only."

However, I've run into a problem, which can be demonstrated by the simple 
context:

context SwitchTest {
  s => {
    Set(FortyTwo=42);
    Set(SixByNine=54);
    switch(${SixByNine}) {
      case 123:
        NoOp(123);
        break;
      case ${FortyTwo}:
        NoOp(${FortyTwo});
        break;
    }
  }
}

This gets converted by AEL into:

[ Context 'SwitchTest' created by 'pbx_ael' ]
  's' =>            1. MSet(~~EXTEN~~=${EXTEN})
                    2. Set(FortyTwo=42)
                    3. Set(SixByNine=54)
                    4. Goto(sw_5410_${SixByNine},10)
                    5. NoOp(Finish switch_SwitchTest_5410)
  'sw_5410_' =>     10. Goto(sw_5410_.,10)
                    11. Goto(s,5)
  'sw_5410_123' =>  10. NoOp(123)
                    11. Goto(s,5)
  '_sw_5410_.' =>   10. Goto(s,5)

So, there was no implementation of the "case ${FortyTwo}" match.

Am I misundertanding "they can be constants, or ${var} type references only."?
