Title: fix build failure against ghc-HEAD (die clast, FlexibleContexts)

The name clash failure is easy:
> Ambiguous occurrence ‘die’
> It could refer to either ‘Main.die’, defined at src/Main.lhs:291:3
> or ‘System.Exit.die’,
> imported from ‘System.Exit’ at
src/Main.lhs:28:3-20

The type inference constraints with language extensions are more tight now:
