A good, standard OO API wrapper for Subversion would be an extremely
good thing, IMNSHO. Even if existing clients didn't adopt it, we could
use it instead of the C API to generate script bindings -- Perl, Python
and (presumably) Ruby bindings would be much better if they were based
on the same, solid OO API.

Given how heavily the C API relies on pools, I suspect that designing a
good C++ wrapper would not be the simplest thing in the world. Whilst I
support the idea, I'd personally rather live without C++ than support a
half-baked design.
