Lesson 20 Step 4 #171
Description
In the middle of this section, the tutorial states:
"Let's activate this warning with the default ones:
#warnings "+a-4-6-7-27..29"
We can now implement a function that does not use all the labels and see what happens:
let abs { x } = x"
It seems to be suggesting that we're about to get an error.
Interestingly enough, there is no error. Everything compiles just fine.
Perhaps the terminal's more up-to-date than the lesson steps?
