<interactive>:12:1: error:
• Unacceptable result type in foreign declaration:
Safe Haskell is on, all FFI imports must be in the IO monad
• When checking declaration:
foreign import ccall safe "sin" c_sin :: Double -> Double
<interactive>:13:1: error:
• Variable not in scope: c_sin :: t0 -> t
• Perhaps you meant ‘c_sin'’ (line 8)
