String& operator<<=(const String& s)
"Deep" assignment. It is equivalent of standard assignment followed by Shrink operation (in other words, internal buffer gets reallocated to the exact size of source).

Hmmm, that means that I can replace <<= with = in the new C++?

Yes.

Originally (pre 2013) <<= meant deep copy and 'other data assignement'. Deep copy meaning is deprecated in favor of 'clone'.

With String, it was always pointless anyway, so it is now removed.

Witch containers, use a = clone(b). Or a = pick(b) if you want move. frankly, pick is now 100% synonyme for std::move, so you can write a = std::move(b) too...

We still use <<= for widget data assignment.
