proxy_as should always introduce a WITH clause

Arguments against?

I think the with would cut off your access to identifiers earlier in the chain unless it also brings along the ids already declared, right? I often drop into Core::Query to express something in the DSL, write part of a query, and then proxy_as to get back to QueryProxy but ultimately pluck something from earlier in the chain.

I just noticed that you can do with('*'), which might seem pointless but it can allow you to make MATCH clauses when you've previously done OPTIONAL MATCHes.

We still need to dig into potential issues, but I wanted to note that while I was thinking of it ;)
