`

###Sample Usage

> See examples.


###Methods

> Arguments within [ ] are optional.

`javascript
/*
* Return a function bound to a scope and a series of arguments,
* passed through an array.
*/
Funny#bind( Function fn, Array args [, Object scope ] ) : Function

/*
* Empty function.
*/
Funny#emptyFn() : undefined

/*
* Return input as output.
*/
Funny#echoFn( Object obj ) : Object

/*
* Shortcut for ( typeof fn === 'function' ) ? fn : emptyFn;
*/
Funny#checkFn( Function fn ) : Function

/*
* Shortcut for Array.isArray( arr ) ? arr : ( wrap ? [ arr ] : [] );
*/
Funny#checkArr( Array arr, Boolean wrap ) : Array

/*
* Check if n is a number, otherwise it returns vice.
* Shortcut for ( ( typeof n === 'number' ) && ! isNaN( n ) ) ? n : +vice;
*/
Funny#checkNum( Number n, Number vice ) : Number

/*
* Return a new function, bound to fn.
* For example, to create a shortcut for toString.call:
*
* var toString = Funny.mock( toString || Object.prototype.toString );
* toString( [ 1, 2, 3 ] );
*/
Funny#mock( Function fn ) : Function

/*
* Recur is a method to bypass the tail call optimization problem,
* this method use a 'trampolining' method for recursion, code was
* based on https://github.com/Gozala/js-tail-call.
*/
Funny#recur( Function fn ) : Function

/*
* Shortcut for Array.prototype.slice.call
*/
Funny#slice( Object arguments ) : Array

/*
* Shortcut for Array.prototype.push.apply
*/
Funny#push( Array dest [, Array source ] ) : Number

/*
* Shortcut for toString.call || Object.prototype.toString.call
*/
Funny#toString( Object obj ) : String

/*
* Trigger a function execution before another one.
*
* NOTE: regardless of the order of activation/execution,
* the 2 functions will run in parallel; it means that the first
* function could also end its execution after the second one.
*/
Funny#trigger( Function fn, Function ln [, Object scope ] ) : Function

/*
* Chaining functions execution. Every function will be executed
* in order of appearence and will receive a callback argument to
* execute the next function, optionally with some desired arguments.
*
* If left was true, the callback is passed as the first
* argument to the function, otherwise as the last argument.
*/
Funny#chain( Array functions [, Object scope [, Boolean left ] ] ) : Function

/*
* Pre-execute a fn before another one.
* The pre-executed function should call the callback,
* passed as an argument, to launch the second function.
*
* If left was true, the callback is passed as the first
* argument to the function, otherwise as the last argument.
*
* It is a shortcut for Funny#chain( [ fn , ln ], .. )
*/
Funny#precede( Function fn, Function ln [, Object scope [, Boolean left ] ] ) : Function

/*
* Pre-execute a fn before another one ( expressed as an object property ),
* replacing the latter with the fused function.
*
* The pre-executed function should call the callback, passed as an argument,
* to launch the second function.
*
* If left was true, the callback is passed as the first argument
* to the function, otherwise as the last argument.
*
* It is a shortcut for: obj[ fname ] = precede( fn, obj[ fname ], env );
*/
Funny#fuse( Function fn, Object obj, String fname [, Object scope [, Boolean left ] ] ) : Function
