Yup, the spec is also really vague on if clear() actually releases memory. AFAIK the only "correct" way to actually clear a vector is "vec = std::vector<T>()" w

Yup, the spec is also really vague on if clear() actually releases memory. AFAIK the only "correct" way to actually clear a vector is "vec = std::vector<T>()" with the STL.

Actually you'd have to try harder: even this might leave the current capacity unchanged. The blessed idiom is vec.swap(std::vector<T>()); c++11 added shrink_to_fit which is a non binding request to reduce capacity.
