do we have a non-member reset() somewhere? Something like
template <typename T> void reset(T& t) { std::swap(t, T()); }
(of course to be refined...)
why not :
template <typename T> void reset(T& t) { t = T(); }
swap() is typically as fast as or faster than copy assignment,
Not for many types that one might like to reset, such as pointers, shared_ptr<T>, and integral types. -- Dave Abrahams Boost Consulting www.boost-consulting.com
