Camping and DBI

[Eric Mill]

Maybe, but does that benefit you?  Constants aren't allowed to be set
more than once (when you first define them), so using one as a DB
connection might potentially cause problems if you ever reset it.
It's also "unfashionable" in Ruby land to use constants over instance
variables for this work.
