Yes, I would prefer to create a variable naming those expressions,
but these are all still simple enough that I would expect to have
to read them. (I like constructions that get ugly just a bit faster
than they get hard to understand.) If I have to parse any of them,
the ones at the bottom are less difficult than the ones at the top.
I totally disagree. I found the second one the easiest to read, and outside a function call (or other complexity, the
parens wouldn't be needed.
