Changed readArray to unsafeRead, and it is 47 times faster now.
I must say I am pleasantly surprised that GHC managed to unbox everything there was to unbox without much annotations. For 5MB file the program allocated only 192KB in the heap. Especially optimisation of higher-level constructs like 'fmap (toEnun . fromEnum) ...' is very nice.
Now I like to see an implementation which is both elegant and fast ... :-)
