i used this script, a little clunky but it got the job done
```bash
for file in `find . -type f -print | grep '\.go'`; do
sed '1,/^\/\/ limitations under the License.$/d' $file > $file.tmp;
result=`cat $file.tmp`
if [[ result != "" ]]; then
gofmt $file.tmp &> /dev/null;
if [[ $? == 0 ]]; then
mv $file.tmp $file && gofmt -w $file;
else
rm $file.tmp;
fi
else
rm $file.tmp;
fi
done
```
Usage:
`IncludesColumn(Intersect(Row(a=1), Row(b=2)), column=10)`
The above query will return a `bool` indicating whether the
intersection of rows a-1 and b-2 contains column 10. Because
a single column is specified, this executes on a single shard
(shard=0 in this example).
