Sometimes types unfortunately have implicit conversion, and if the compiler finds them (I guess that what's common_type deduces?),I might end up with a bogus expression that unfortunately compiles.
Could you give a concrete example (with 3 type clamp)?
enum A{a}; enum B(b); main() { clamp(0, a, b); }
Right. g++ 4.6: warning: enumeral mismatch in conditional expression: ‘A’ vs ‘B’ Is this really the fault of clamp() though? The same 'mistake' can easily be made in normal code. Olaf
