Is there a developer tool, module, or code snippet that will show all the menu items currently configured in a Drupal system?
If not, would it be "safe" to invoke the menu hook myself to collect this information? In other words — do individual menu hook listeners (implemented by module developers) alter system state in such a way that invoking the menu hook twice during a page request would be a "bad thing".
Newish to Drupal, not new to programming. I'm specifically interested in a programmer's view of the menu.
