Description

Can be done by a simple trait vector which is used to pull a tmp variable from a cache. Can probably default to cache.tmp since that's common, and then overload as necessary.

Contributor guide

Research direction
Create a trait vector that retrieves temporary variables from a cache, defaulting to `cache.tmp`, and overload as needed to reduce allocations in auto dt.
