scheme sort of has this dichotomy that merges the concept of code and
data.  It's sorta the nature of the beast.  *shrugs*

Reducing complexity is always a good thing, provided you don't lose
(real, usable) functionality in the process.

I feel the same way about QOF and the hole query/save object system.
I feel the same way about all the gpointers we have everywhere.  I'd
much rather use a type-safe object system But you know what?  That's a
LOT of work.  So I need to either ignore it, or make small adjustments
here and there.

Agreed, it needs to be an evolution.  Small steps.  Let's get the API
better documented.  Let's add the helper functions we need to make it
easier to use.  Let's flush out the API that you need to get the
functionality you need.
