Let queries pull data from other queries
Logically, parts of queries can be shared between queries. For example, both "Types that could have a lower visibility" and "Potentially dead Types" need to ignore classes with only const fields. I would like queries to be able to build on the results of other queries, much as C# methods reduce code duplication by using other methods.
This is a feature we'd like to provide, let's see how many votes it gets, this will help prioritize it.
