Everything else I said are just explanations (why not updateDynamicOpts and why ghci can't set -XHaskell2010 as the default, but we can). deposit :: NodeType -> NodeType -> Amount -> Node deposit (Income income) (Account bal grow) amount = Account (bal + transfer) grow where transfer = case amount of AbsoluteAmount amount -> Not the answer you're looking for? http://kiloubox.com/parse-error/parse-error-possibly-incorrect-indentation.html

My tests show they are examples of the options that don't work OK as dynamic options (so they could be black listed for updateDynamicOpts, see #185). linking ...

This is because elem doesn't 'know' that the lists you're looking through are sorted in ascending order.

I tried indenting it with tabs too, but it didn't work. Loading package base ... linking ... C++ delivers a clear message explaining how to fix the error.

However there's a nice style guide concerning indentation among some other things.

That is, we make IdeSession do the -XHaskell2010 but leave you responsible for adding -XNondecreasingIndentation and whatever else. https://mail.haskell.org/pipermail/beginners/2009-March/001103.html Here you can also ask for feedback on your code and ideas.

In the C++ version, I forgot the parentheses, and in the Haskell version I forgot the else.

For example, it doesn’t address Paul’s last point about type errors being verbose. What kind of bugs do "goto" statements lead to?

It tells me that there are not enough arguments in my function call.

How should I know this is related to a missing do? And it should be possible for the user to set the mode to Haskell98, if he chooses so. That sounds good to me. The error message is simply not helpful.

At least in my current tests (7.4.2, ghci) it does work OK when set dynamically. Wow, Hakell’s error message is quite the mouthful this time. ofcourse! http://kiloubox.com/parse-error/parse-error-parse-error-unexpected-t-object-operator-in-joomla.html My solution is the following.

How can I copy and paste text lines across different files in a bash script? But in some cases, the "default mode" still behaves like Haskell98: http://www.haskell.org/ghc/docs/7.8.2/html/users_guide/bugs-and-infelicities.html#haskell-standards-divergence I've tested, using the tiny snippet from this ticket, that regarding our syntactic problem, the default mode's behaviour agrees linking ... It works like this because otherwise is defined as otherwise = True so it's not a keyword like else, it's just a human-readable "always", and since the guards are tried top-to-bottom,

Are there any historically significant examples? This patch doesn’t completely fix ghc’s problem with poor error messages. We now think specifying nothing and getting GHC's default is equivalent to -XHaskell2010 -XNondecreasingIndentation. Browse other questions tagged haskell or ask your own question.

If the user wants another mode, she just overwrites defaultSessionConfig and restarts the session, regardless which of the three modes she wants. This is what gave you the indentation error.
