* Keep parens in cases like `f <| (g << h)`, `x + (y ++ z)`, etc.
* The order of operations in `x > (y < z)` or `x <> (y <> z)` is not necessarily immediately obvious, and there are built-in operators in this class like `<|` for which the associativity of the underlying operation depends on the types of the operands.

Description
Keep parentheses for non-identical infix operator pairs that have the same precedence, e.g.:
etc.
We still offer to remove them when both operators are the same, e.g.:
except for the left-associative "relational" operators (
=…,|…,&…,$…,>…,<…,!=…, including|>,<|,>>,<<, etc.), where the order of operations is often arguably non-obvious:Checklist
