[11 of 31] Compiling HOC.Exception ( HOC/HOC/Exception.hs,
dist/build/HOC/Exception.o )
HOC/HOC/Exception.hs:33:12:
Ambiguous type variable `a' in the constraint:
`base:GHC.Exception.Exception a'
arising from a use of `throwIO' at HOC/HOC/Exception.hs:33:12-22
Probable fix: add a type signature that fixes these type variable(s)
