Not really what I was looking for but I may end up using it.

What I wanted is to hide the Monad and Array and have it inferred from the
context of the array

STArray or STUArray when run in the ST monad with runST(U)Array, IOArray or
IOUArray when used in the IO monad, etc...

I'm not sure it's the right thing to do. I may create more troubles than I
solve. I was just trying to keep things as generic as possible.

Thanks for your reply,

Olivier.
