@tembok where do you read that? as long as A is pure. It's fine to directly call A inside B. 

And in the case A is impure and B needs some thing from A, the result of A is the one that should be passed along rather than A itself. Passing A would make B impure.

The only time you need to pass a function is when you need different functionality depending with the same structure or when you need dependency injection

@tembok even then dependency injection is reserved to the outer most function that talk to the outside world
