Comment (by zzzeek):

 maybe column.make_proxy() should have a little more going on - not just
 _proxies, but also, "_lookup_equivalent", which is flagged for both a
 select() and a text() when it makes the initial column proxy.  that gets
 added to the result_map. _lookup_equivalent gets erased for any proxies
 subsequent to that, e.g. such as aliased().

 the fact that a select() is never embedded as a subquery without being an
 alias might work well with this concept.
