Hello
I just want to make some questions on the new dispatch benchmark mainly
on what is required and what not.
Would the following be legal:
* BottleStates are immutable - thus making a flyweight pattern make
little sense. What does flyweight pattern mean in a language that does
not have pointer equality?
data BottleState a = Full | Empty | Sealed | Subclass a
data PBottleState = UPFull | UPEmpty | PUnsealed | PSealed
type BS = BottleState PBottleState
* "PressurizedBottle is a subclass of Bottle"
But they have equal contents (a PressurizedBottle is a Bottle and adds
no new members). Is using types like the following cheating?
type Bottle = IORef BS
type PBottle = IORef PBottleState -- (or BS if so required)
newBottle = newIORef Full
newPBottle = newIORef UPFull
