Why is this such a problem?

You can still write and compile very beautiful programs with both GHC  
and UHC.

And keep in mind that the UHC compiler is probably not designed to  
replace GHC and to be fully compliant with the Haskell 98 standard. It  
still has a very useful place in education and is certainly worth  
looking at.

It is intensively making use of the attribute grammar system to  
perform traversals over the different internally used languages. This  
is a very different approach from what GHC does which makes it very  
interesting from an educational and scientific point of view.

I encourage you to take a look inside, it is reasonably easy to grasp  
what going on inside of UHC.
