uvector has (almost) nothing in common with DPH's API. It is forked  
off the flat sequential array layer which DPH uses internally and  
which the users aren't supposed to even know about. Also, the fork  
happened quite a while ago, DPH has changed a lot since then and is  
going to change a lot more in the future. My plan is to eventually use  
my vector package to replace those flat arrays but sadly I don't have  
a lot of time to work on it (although vector is quite usable by now  
and even implements recycling which should improve DPH's performance  
by quite a bit). The fact that everything DPH depends on will have to  
be distributed with GHC doesn't help, either, since adding a new  
package into the mix is a pretty big step.
