[Haskell] TArray?

Are there plans to include a mutable array for use in the STM monad, or a good reason for why this is not needed? Also, an unboxed version would be nice. A workaround is IOArray with unsafePerformIO wrapped in the STM monad, but it would be preferable if multiple threads could write to the same array without causing conflicts unless they write to the same index. /S -- Sebastian Sylvan +46(0)736-818655 UIN: 44640862
