Double stacktrace with errorWithCallStack
Hello,
The documentation of https://hackage.haskell.org/package/base-4.10.0.0/docs/GHC-Stack.html#t:CallStack uses the following code:
errorWithCallStack :: HasCallStack => String -> a
errorWithCallStack msg = error (msg ++ "n" ++ prettyCallStack callStack)But this is confusing because now you will get two stacktraces. One from error and one inside error with prettyCallStack.
