I don't find that more readable at all. I prefer:

    if deleteUser
      user.delete()
    end

It's easier for me to read. It doesn't try to hide away logic. And if the line gets longer if the conditional gets more complex or I want to add an else I can without reformatting.

It works well for some cases. You end up with

return if a.nil? return if attempts < max_attempts

In this case "return if" becomes like a keyword and you can ignore it and focus on the rest of the expression. It also seems very readable for other simple values like `return false if ...`. But I agree, as soon as the code to the left of the `if` gets non-trivial it is harder to read.

It's subjective, the point is that some people prefer it.
