OK, I'm up for that. I have a "hard real time deadline" today but am
willing to give it another go afterwards.

Perhaps I should email you off-list once I get the project open again in
the next day or two? Or if others say they're interested we could take
it to the -users list.

I know. FWIW, I felt like I could get through the template errors
reasonably well.

Hmmmm... I'm keeping an open mind. :-)

I made a generative template system for a lightweight key-record data
persistence system here at work. The record types are usually updated by
someone else...who doesn't even know much C++! So I know it can be done.
