Thread-based programming calls for manual management of thread exhaustion, oversubscription, load balancing, and adaptation to new platforms, while task-based programming via std::async with the default launch policy handles most of the issues for us.

Lambdas are more readable, more expressive, and may be more efficient than using std::bind.

C++14 introduces generic lambdas, which use auto in their parameter specifications.

Use init capture to move objects into closures in C++14; emulate init capture via hand-written classes or std::bind in C++11.

Default by-reference capture can lead to dangling references; default by-value capture is susceptible to dangling pointers, while misleadingly susggests the lambdas are self-contained.
