A lot of credit also goes to Andrei for design issues, and some others 
who also submitted bugzilla reports and patches, such as Rainer Schuetze.

I don't think the min() example is that useful, I can't think of when I 
ever needed it. But min() is important as one of those metaprogramming 
"litmus tests" that are the canary that indicates whether one has a 
complete system or not.
