Some features of this module: - Preserves function names - Uses a native promise implementation if available and tries to fall back to a promise implementation such as bluebird - Converts multiple arguments from the callback into an Array, also support change the behavior by options.multiArgs - Resulting function never deoptimizes - Supports both callback and promise style An added benefit is that thrown errors in that async function will be caught by the promise!
