in the same vein, please name associative structures (hashes, maps, dictionaries, etc) as value-type-by-key-type (for example "username_by_id", rather than "username_lookup" or such. Conventions like these don't have an impact one-by-one, but rather when applied to a body of code as a whole. In this case when one has to do one lookup by the result of another the explicit "x-by-y" naming really helps reassure me the right values are being looked up!
