I'm trying to create a hash table. Yeah, I know, don't use hash tables, but I need to create something I'm familiar with, not something I've never worked with before. What's wrong with this code?
import Prelude hiding (lookup)
data MyHashTable = HashTable String Int
dummy:: String -> Int
dummy s = 7
ht = MyHashTable.new (==) dummy
[michael at localhost ~]$ ghci hash1
