C++ Standard Library "Little Things”
summary
Covers concrete small library additions and real tradeoffs: feature-test macros distinguish header presence from usable features; exchange avoids move-from state and has no extra debug cost; clamp and starts_with/ends_with simplify common code; associative containers expose node_handle lets you extract, mutate key, reinsert and support splice/merge without reallocating; unordered containers often use linked nodes under the hood; contains fixes count inefficiency; and parallel sort wins from ~1,000 elements on both laptop and 32-core hardware.
