Chapter 8. Working effectively with multi-argument functions
This chapter covers
- Using multi-argument functions with elevated types
- Using LINQ syntax with any monadic type

Remember, effectful types are types such as Option (which adds the effect of optionality), Exceptional (exception handling), IEnumerable (aggregation), and others. In part 3, you’ll see several more effects related to state, laziness, and asynchrony.
