Unless I'm mistaken, you're talking something similar to Andrei 
Alexandrescu's ENFORCE:
http://www.cuj.com/documents/s=8250/cujcexp2106alexandr/

As a side-note, I'm implementing SMART_ENFORCE in the smart_assert library.
Unfortunately in the latest months I did not have time for it. Hopefully 
I'll have some time in the next couple of weeks to port it to vc7.1 and 
post a new version.

Best,
John
