a nube question

[Rob Dunne]

Hi All,

I have a problem loading any source file into ghci. I get lots of

"Not in scope" error messages. I am just cutting and pasting these examples from various tutorials 

such as

https://downloads.haskell.org/~ghc/7.8.1/docs/html/users_guide/loading-source-files.html

so the syntax should be correct. 

See the example below. I must be missing something very fundamental!

Bye

Rob

The course material turns off implicit Prelude with a .ghci file. Try it in a directory without .ghci and make sure there is no ~/.ghci file.
