    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

## Usage

```javascript
var thunk = require( '@stdlib/function-thunk' );
```

#### thunk( fcn\[, ...args] )

Returns a [thunk][thunk] (i.e., an anonymous function having arity `0` and which invokes a provided function with specified arguments).

```javascript
var add = require( '@stdlib/number-float64-base-add' );

var f = thunk( add, 2.0, 3.0 );
// returns <Function>

var v = f();
// returns 5

// ...

v = f();
// returns 5

## Examples

var add = require( '@stdlib/number-float64-base-add' );
var decorateAfter = require( '@stdlib/utils-decorate-after' );
var discreteUniform = require( '@stdlib/random-base-discrete-uniform' ).factory;
var thunk = require( '@stdlib/function-thunk' );

function log( v ) {
    console.log( v );
}

// Create a PRNG for generating uniformly distributed pseudorandom integers:
var randi = discreteUniform( 100, 1000 );

// Randomly delay evaluation of various thunks...
var i;
for ( i = 0; i < 10; i++ ) {
    setTimeout( decorateAfter( thunk( add, i, i+1 ), 0, log ), randi() );
