The trick is to break that (on the dots) into three const assignments with descriptive names. Practically self-documenting, easily debuggable.

If you don't use the builtin transformations, you'll just end up re-implementing them, poorly. And adding to the cognitive overhead with new concepts. And I have to read your code with a fine-toothed comb to ensure it's really side-effect free. I don't advocate turning everything into a named function as in your example though, short one-off functions should all be inline IMO.
