Re: [boost] Improving the assignment operators of various Boost types

One downside is that self-assignment is made suboptimal. My typical operator= implementation is:

T& operator= (T const& that) { if (this != &that) T(that).swap(*this); return *this; }

Not sure, however, if it is critical enough.

In practice I haven't written any interesting code that does self assignment. Perhaps you have. In my code I'd consider this a pessimization. Thanks, Michael Marcin
