The copy-and-swap idiom is certainly very cute, but often causes unnecessary copies. My commitfedafb9352did exactly that, unfortunately. Restore the exact same code for the copy-assignment operator as before commitfedafb935, and add a more efficient implementation for the move-assignment operator. As explained by Howard Hinnant in [1] and [2], if some particular piece of code really needs a strong exception safety guarantee, one can easily add a specific method for that; this is not a valid reason to make the code slower for all other places that have no use for such a guarantee!
