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.

What about exception safety guarantees of assignment vs. swap?

What about 'em? Speaking generally, both are basic guarantee operations.

I thought that swap is often (not always) a function which doesn't throw, e.g. containers' x.swap( y ). If it is, it would make reset a function with the strong instead of the basic exception guarantee. But then, this might not be general enough to be worth the trouble... OK, forget about it :) Regards, Daniel
