## Usage
```javascript
var papply = require( '@stdlib/utils/papply' );
```
#### papply( fcn\[, ...args] )
Partially applies function arguments.
```javascript
function add( x, y ) {
return x + y;
}
var add2 = papply( add, 2 );
var sum = add2( 3 );
// returns 5
sum = add2( 7 );
// returns 9
```

<section class="notes">
## Notes
- The implementation does **not** set the `length` of the returned function. Accordingly, the returned function `length` is **always** `0`.
- The evaluation context is **always** `null`.
