Is there in Haskell a non monadic function of type a -> a -> Bool which test for physical equality of two values? It would return True if only if both values are the same object in memory.
IIRC "observable sharing" does similar things. Sönke
For instance:
value1 = "good" value2 = "good"
eq value1 value2 => False
value1 = "good" value2 = value1
eq value1 value2 => True
