So a realistic example: purchaseCardContents calls purchaseCardContents which calls toPurchaseCardContent several times.
Now I need a class FormatSavings in the last function toPurchaseCardContent.
How do I get it there? When using a class for the whole logic, I just inject it through the constructor.
The issue here is that toPurchaseCardContent doesn't know anything about purchaseCardContents so I would need to pass-through that class and everything else it needs.

Maybe the better question is: How do I get / pass dependencies I don't want the caller to bother about in functional programming?

This code seems to have a quite narrow scope, I don't see how you could make something generic or apply some pattern I know (I don't know all of them though, far from this)

I think I'd have a FormatParams class if I had your use case
