 Note that all entities are memoized, so rewinding the iterator will **not** cause it to request pages again.
 Use **reset** for this kind of behaviour.

         Currently only `per_page` is used, which controls how many entities in a page can the iterator request.
 
-- next()
+- `next()`
 
     Returns the next element or `undef` if there are no elements left.
     Automatically downloads next page from API if required.
 
-- reset()
+- `reset()`
 
-        $iterator->reset

     Resets the iterator to the original state that can be reused.
     Clears all data and error flags, so that the requests can be issued again.
 
-- rewind()
+- `rewind()`
 
-        $iterator->rewind
+    ```{.pl}
+    $iterator->rewind
+    ```
 
     Resets the iterator to the position before the first element, so that the call to `next` will return the first element.
     Note that this will **not** cause the iterator to re-download all pages.
     Use `reset` for this purpose.
 
-- all()
+- `all()`
 
-        my @items = @{ $iterator->all };
+    ```{.pl}    
+    my @items = @{ $iterator->all };
+    ```
 
     Downloads all pages and returns an arrayref of all elements.
 
 ## Internal methods
 
-- next\_block()
+- `next_block()`
 
     Tries to download the next page from the GitLab API.
     Returns false if no page left or an error occured.
