Yes, code review is arguably worse, but most people who write Java do so with an IDE and the type is never unknown at that point.
Also, if your function is big enough to where the type of var is not very clear, it likely shouldn’t be passing code review regardless.
This reminds me of a developer writing in jRuby because "it was better". While he was in the company he'd still give support to his own works, after leaving nobody else wanted to pickup those "better" things and would prefer to write workarounds to the tool, it effectively became a black box that few could improve and even worse to test. As result, those portions had to be rewritten in proper Java so that we'd be able to deeply measure/test and improve.
Never again.
I’m in agreement that when the information isn’t in the rvalue that you shouldn’t use var.
