from the previous
discussion(https://github.com/apache/spark/pull/14389#issuecomment-236591342):
> We also need to add some checks before applying the type widen rules, to
avoid conflicting with DecimalPrecision, which defines some special rules for
binary arithmetic about decimal type.
Have you tried this?
`push type coercion into each expression` is also in my plan, but it would
be a very large change, we should have a design doc first and discuss it with
some people. So I'd like to do this small refactor first, what do you think?
