Review Comment:
```
* static method tupled()scala.Function1 in class
org.apache.spark.sql.sources.And does not have a correspondent in current
version
filter with:
ProblemFilters.exclude[DirectMissingMethodProblem]("org.apache.spark.sql.sources.And.tupled")
```
I don't understand how `tupled` got broken by this change. Also I wonder
with tasty we should have better binary compat.
I think we need consultancy from compiler people.
