More array shapes in the framework code!

[tamiroh]

A few months ago I submitted a PR that uses the array shape notation to write the return value in more detail.

      * Parse the route action into a standard array.
      *
      * @param  callable|array|null  $action
-     * @return array
+     * @return array{uses: callable|string, controller?: string, ...}
      *
      * @throws \UnexpectedValueException
      */

Unfortunately it was closed.

However, I think such detailed types are useful to improve the readability of the framework code. This is especially true where arrays are complicated, such as the above. In fact, there are already several places in the framework where array-shape is used.

Any opinions on this?

I would like to bring the above PR to merge. Furthermore, if possible, I would like to apply the array shape typings to other types as well.

I agree. But I suggest php 8 attributes for that.
