Reading the first paragraph "Introduction to Uniqueness Typing" of this paper should help you with that question - http://www.st.cs.ru.nl/papers/2008/vrie08-IFL07-UniquenessTypingSimplified.pdf > BTW, it seems that to verteran Haskellers, the speed of Data.HashTable > is not a concern to them as they said they don't see the need of > that(mutable hasktable) in their usage.
