I agree that it's an issue. In my own defense, what I meant was not that I
didn't think people would use more than one DB. I actually have several apps
(not yet converted to Lift) that use 4 or more persistence units that
represent various legacy databases. Rather, I failed to realize the problem
In Derek's defense, it's not how objects in classes work but how Lift
RequestVars work. Scala objects in classes aren't global singletons, just
per-class-instance singletons. But a Lift ReuqestVar object in a class is
pretty much a global singleton (unless you do some hacking like Derek did).

You made an assumption and programmed a solution based on the knowledge you

the simplest solution that fits. If it need to be changed due to changing
requirements, thats fine too. There is a tradeoff in creating a overly

Are you being honest here Derek? Was not the real problem that you
failed to truly embrace the shape of the paradoxical combinator?

Isn't this just the result of JIT development? Don't need something
right now, don't implement it. If you need it later, refactor.
I'm probably looking at this too much from a low level grunt developer.
I understand that when developing a framework or anything with a public
API these are
JIT development ;)
In all serious though, its better to have a minimal set of features that
work well and can be refactored effortlessly, than to define an entire
API and have everything need to change in an updated release.
And at the speed this particular fix went in, its hardly hindering

The short answer is no. The longer answer is

You have just demonstrated a process that i have been talking about for the
last 15 years. People have a blind spot when it comes to thinking
compositionally. They think -- almost to a person -- about god's eye view
solutions where there's only one of some key solution component.
I think you have just volunteered to help refactor this code to make it more
composition friendly :)

No doubt it is extremely tough to think compositionally, and it's all too
