I haven't gotten to learning about them in detail yet, but my hope was
that STUArray was like vector<T>  in C++, and STArray was like
vector<T*>. Both are fairly general.

So if I need a array of complex numbers in Haskell, will I need an
extra level of indirection compared to C? And in addition to that some
serious issues with GC speed if those arrays need to be mutable?
