Customisation point for the async package or any concurrency
framework that defines a "then" operation. Assign the result of
<code>async_ops()</code> to the <code>.__coro_async_ops__.</code> symbol in your
namespace.

Provides 'coroutines' for R, a family of functions that can
be suspended and resumed later on. This includes 'async' functions
(which await) and generators (which yield). 'Async' functions are
based on the concurrency framework of the 'promises' package.
Generators are based on a dependency free iteration protocol defined
in 'coro' and are compatible with iterators from the 'reticulate'
package.

async_ops function

<dl><dt>package</dt>
<dd>The package name of the framework as a
string. <code>async()</code> and <code>async_generator()</code> check that the package
is installed at runtime.</dd>
<dt>then</dt>
<dd>A function of two arguments. The first argument is a
promise object (as created by <code>as_promise</code>). The second argument
is a callback function that must be called once the promise
object is resolved.</dd>
<dt>as_promise</dt>
<dd>A function of one argument. It should be a no-op
when passed a promise object, and otherwise wrap the value in a
resolved promise.</dd></dl>
