But I spent years learning && and ||, when I read code, these patterns jump out at me. Sure they aren't as "readable" but we're writing a program here, not the Illiad. I write in a programming language, not english, if I wanted to write in english, I'd go be an author, or a journalist. As people have mentioned, it only makes the code more readable (and even that is under debate) for english-speaking users, foreign language users are at even more of a disadvantage, since the have an extra step of analysis to figure out what it means, especially since there might not always be a simple translation. Don't think of && and || as `and` and `or`, think of them more as logical conjuction and disjunction, they are predicate operators. And if we want to get into "proper" symbols for logic, we should be using ∧, ∨, ⊕, ¬ for and, or, exclusive or and not, since those are the proper boolean algebra symbols. -- James Miller
