> Our current BinaryExpression abstract class is not for generic binary expressions, i.e. it requires left/right children to have the same type. However, due to its name, contributors build new binary expressions that don't have that assumption (e.g. Sha) and still extend BinaryExpression.
> We should create a new BinaryOperator abstract class with this assumption, and update the analyzer to only apply type casting rule there.
