It is generally acknowledged that the array types bundled with GHC
have serious shortcomings, such as for example the one you just
pointed out. There is not, however, a consensus on how to change them.

To solve your particular problem, I would suggest looking up the
storablevector package on Hackage, which I know can handle arbitrary
unboxed elements.

That said, I'm sure someone will be along shortly to give you the full
story. :-)
