I agree. BTW Howard Hinnant's proposal N2199 
(http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2199.html) 
introduces correct C++ min/max functions that take 175 lines and 
introduce 10 types and 12 specializations. (Proposal was rejected.) The 
power of min/max is about on a par with D's.
