An example where I disagree, and use 1-letter names daily: arrow functions in both Java and JS.

`usersList.stream().forEach(u -> someSet.add(u))`

It's immediately obvious that u is a user in usersList. I realize that it's debatable if u is really more readable than spelling out user, but I prefer it, and I don't think anyone is going to be confused by it. If the chain does get really long, also, I will spell it out explicitly.

Shouldn't you be able to write that as `usersList.stream().forEach(someSet.add)`

For Javascript at least that would work.

I haven't written Java since like java 5, but I believe java 8 has syntax for this as well:

`usersList.stream().forEach(someSet::add)`

Sure, for a lambda I think it’s arbitrary. For larger functions / classes it matters
