 These flags help catch two common issues in Kyo applications:
 
 1. **A pure expression does nothing in statement position**: Often suggests that a Kyo computation is being discarded and will never execute, though it can also occur with other pure expressions. Common fixes include using `map` to chain transformations or explicitly handling the result.
 
-2. **Discarded non-Unit value**: Most commonly occurs when you pass a computation to a method that can only handle some of the effects that your computation requires. For example, passing a computation that needs both `IO` and `Abort[Exception]` effects as a method parameter that only accepts `IO` can trigger this warning. While this warning can appear in other scenarios (like ignoring any non-Unit value), in Kyo applications it typically signals that you're trying to use a computation in a context that doesn't support all of its required effects.
+2. **Unused/Discarded non-Unit value**: Most commonly occurs when you pass a computation to a method that can only handle some of the effects that your computation requires.

 > Note: You may want to selectively disable these warnings in test code, where it's common to assert side effects without using their returned values.
