Workaround: `unqualify(T)`: Now Look What You Made Me Do

Here's a workaround for the bug. It's a version of `Unqual` that 
uses a completely different mechanism to get at the 
qualifier-less type: it looks up a symbol by that name in the 
surrounding aggregate, or tries to jump to the "parent of the 
first member".

Even though it "works" for our usecases, this clearly does not 
spark joy.
