Just rediscovered function composition.

composer.js

function composer(){
	var transforms = [].slice.call( arguments );

	return function functionWrapper( handler ){
		return function transform(){
			var ctxt = this;
			var args = [].slice.call( arguments );

			transforms.forEach( function applyTransform( transform ){
				transform.apply( ctxt, args );
			} );

			return handler.apply( ctxt, args );
		};
	};
}
