Maybe... later...
Right now the *only* thing we wanna do *first* is the conversion. Which is
a huuge undertaking in itself.
So please no more unrelated changes and "it would be good to do this and
that." That can be done later.
If we find a bug while doing so then it is very likely an existing bug which
we'll fix immeditely and continue with the conversion.
Once everything has been converted and the dust settles, *then* w can do
improvements ontop.
Thx.
