Description of the change
This PR adds
clone :: forall h a. STArray h a -> ST h (STArray h a)to the Data.Array.ST module.It makes a mutable copy of a mutable array.
This is similar to the
clonefunction in the Haskell moduleData.Vector.Mutable.This is equivalent to
unsafeThaw <<< freezebut more readable.I need it in one of my projects.
