My first interesting observation is that GHCi (run by `cabal repl`) can load all modules. Yes, cabal repl works for me also {{{ ghc -V The Glorious Glasgow Haskell Compilation System, version 7.10.1.20150630 cabal get -s numeric-prelude cd numeric-prelude cabal sandbox init cabal install --only-dependencies cabal repl }}} However after quitting out of the repl, cabal build fails cabal build Building numeric-prelude-0.4.2... ... It hangs after emitting the following {{{ src/Algebra/RealRing.hs:369:6: Warning: Rule "NP.roundSimple :: a -> Word64" may never fire because ‘roundSimple’ might inline first Probable fix: add an INLINE[n] or NOINLINE[n] pragma on ‘roundSimple’ }}}
