The real cheat of examples like this is using only existing functions. Once you add a closure with current Go syntax it goes to 11 on the hideous.

There's some chat about adding some variant of (x, y => z) to Go, though even then you're adding some more symbols to an already symbol-heavy structure and it looks even worse when you're not using x y z but (username, accountId => a few lines of username and accountId being used).

I agree that the code will become unreadable as soon as you try to use inline functions (since there are no lambda expressions). However, the fp style (independent of this library) encourages to decompose the codebase into small and - if possible - pure functions. For testability. Once the code is structured that way, it's no longer a `cheat`, these pure functions can be used right away in function composition to create more complex structures.
