Yes, that worked beautifully! Now I just do (in Python):

Settings().detailThreshold = 10
Settings().verbose = true

Just found it hard to decide whether I should keep the Python wrapper
as close as possible to the C++ library and use "SetVerbose" and
"GetVerbose", or whether to use Boost.Python's really nifty
properties. Well, I couldn't resist! ;)

Do properties currently only handle straight forward single parameter
"setters"? How difficult would it be to allow it to do two parameters,
with e.g. "object.property[5] = 10"? (Or can it do that already?)

Sounds like an idea ...

Thanks again!
