Data.Primitive.TArray.Classic
Description
This module is a drop-in replacement for Control.Concurrent.STM.TArray
in the stm package. It has the same fundamental inefficiency of the
classic TArray, but it's a little faster and more compact.
Specifically, this implementation uses two fewer words of memory
and one fewer indirection per element.
We also add an MArray instance for working in IO that the stm
version lacks.
Finally, the Eq instance for the official TArray is currently a little broken
thanks to a bug in the instance for Data.Array.Array (See GHC Gitlab issue
#18700). We fix that bug here.
