Actually, Freja had its own nearly-complete compiler for Haskell. We
tried to persuade Henrik to release it more widely as "hhc" (hardly a
haskell compiler), but he did not have enough time to support it
properly. Freja/hhc was a native code compiler (sparc only). It was
the first Haskell compiler to deal properly with mutually recursive
modules (you could include many modules into a single source file). The
more serious deficiency was a lack of typeclasses (but I believe Henrik
fixed that in later versions).
