Oh, ok. I assumed from the indentation (you see layout matters!) that it
was a nested function.

Haskell (like Python) is layout sensitive, the indentation makes a
difference. All function definitions in the same scope have to line up
in the same column. So for global/file scope functions they should not
be indented at all.

So the problem with your example was that your second function was
indented.

Write:

globalFunc1 = ...
globalFunc2 = ...

and not:

globalFunc1 = ...
  globalFunc2 = ...

No, only if you want it nested rather than whole file scope.
