Do you find that you often want to start irb in the same object's
context?  That wouldn't be terribly useful for me, but I'm far from
Mr. Every Use Case Ever :)

When I want to get into a new object, I usually just use "irb
that_object" from inside irb.  That allows me to have a clean (and
quick to start) irb most of the time, and be able to jump into any
object I want, rather than having to alter a config file.

Another option that might be cleaner is to hook an environment
variable so you can set it as part of the irb invocation.  An even
better option would be to use an argument for irb, but I haven't
looked into how long that would take :)
