 FastString:     A compact, hash-consed, representation of character strings.
                 Comparison is O(1), and you can get a Unique from them.

 LitString:      Just a wrapper for the Addr# of a C string (Ptr CChar).
                 Practically no operations
                 Outputing them is fast

 Use LitString unless you want the facilities of FastString
