Target program decision tree
Guard (VConstant:0):

	Leaf=VConstant:1
guard(false) =
	Guard (VConstant:1):
	guard(true) =
		Leaf=VConstant:2
	guard(false) =

Source program decision tree
Switch AcRoot:{ 
} Fallback: Guard (Unit ) =
	guard(true) =
		Leaf='Int 1 '
	guard(false) =
		Guard (Int 1 ) =

The two programs are equivalent.
