I'm having a problem in GHCi when loading modules relying on the base-unicode-symbols package. My prompt gives me the following message:

Oki, so I'm answering to myself: the base-unicode-symbols cabal file introduces a quirk concerning 'base' version which hides the symbols in Control.Category.Unicode.
base-unicode-symbols.cabal -- line 42-46 if !flag(old-base) build-depends: base >= 3.0 && < 4.4 else build-depends: base >= 3.0.3.1 && < 4.4 exposed-modules: Control.Category.Unicode
I should contact the maintainer about this … regards, /john
