Currently, a TArray is a boxed Array of TVars. This seems kind of silly. If TArray is used at all, the array should surely be unboxed to reduce indirection. Nowadays, that means futzing with ArrayArray#, but we'll soon have UnliftedArray#.

Indeed. Let's wait for UnliftedArray# and then fix this.

Here seems to be a related and a bit dated ticket: https://ghc.haskell.org/trac/ghc/ticket/634

We now have UnliftedArray#.

Since Array# is now levity polymorphic, this should be relatively easy to implement.
