if-expression does-not require indentation following new-lines, but functions do? Why?

"yay" : String

The = operator is reserved for defining variables. Maybe you want == instead? Or
maybe you are defining a variable, but there is whitespace before it?

3|   f x = 
Maybe <> can help you figure it out.

|   x
<function> : a -> a

I'm not a huge fan of the title of this post BTW... but to your problem:

I was able to reproduce, but it looks like adding a space on the second line makes it work. I agree the error you posted is misleading.
> f x = \
|   x
<function> : a -> a

I'd also be careful in general when writing "long" functions and using the '\' symbol. It is often used for anonymous function definitions.
