Typo in the docbloc

[ncou]

Hi,

Very nice piece of code. I think there is a small typo in the @param values in the MiddlewareFactory class.

https://github.com/zendframework/zend-expressive/blob/master/src/MiddlewareFactory.php#L128

     *
     * @param string|array|**MiddlewarePipe** $middleware
     */
     public function pipeline(...$middleware) : MiddlewarePipe

I think it's "MiddlewareInterface" and not "MiddlewarePipe" for the param value.

If i am right, i can do a PR.

I think it's correct! MiddlewarePipe is a pipeline/queue of middleware.

MiddlewarePipe implements MiddlewarePipeInterface which extends MiddlewareInterface.

[ncou]

yes but the docbloc should say "MiddlewareInterface" because you can also pass some MiddlewareInterface as parameter.

[dudemelo]

You're right, I thought it was @return instead of @param. The prepare method is waiting for fifty shades of type but one of those is MiddlewareInterface.

zend-expressive/src/MiddlewareFactory.php

Lines 63 to 67 in 87d4294

	* @param string|array|callable|MiddlewareInterface|RequestHandlerInterface $middleware
	* @throws Exception\InvalidMiddlewareException if argument is not one of
	* the specified types.
	*/
	public function prepare($middleware) : MiddlewareInterface

@ncou You're correct; please submit a patch.

the PR is here #663
I have listed all the possible @param value who should be the same as the prepare input params.

Sorry for my poor english.

Keep up the good work.
