What bothers me is the self-explanatory properties are lost; I can't figure out what tuple element that means what by just looking at the code. Is it
tie(eval,dev1,dev2) = find_root(...)
or
tie(dev1,dev2,eval) = find_root(...)
?
Instead a struct would be somewhat unambiguous:
template< class Float > struct root_result { Float eval, dev1, dev2; };
root_result<float> r = find_root( ... );
One could always do something like template< class Float > struct root_result : public tuple<Float &, Float &, Float &> { root_result() : tuple<Float &, Float &, Float &>(eval, dev1, dev2) {} Float eval, dev1, dev2; }; And get the best of both worlds. I sort of wish the compiler would create it by magic, though. Cheers, Nicola Musatti
