Looks handy. When you're writing certain types of programs going the opposite way can be useful. For ex I recently added a /debug/:map_id endpoint to a server

Looks handy. When you're writing certain types of programs going the opposite way can be useful. For ex I recently added a /debug/:map_id endpoint to a server I'm writing that just returns format! ("{:#?}", state.maps.get(id)). Obviously that'd be completely inappropriate in many cases, but for this one polling the current state via curl was quite handy.
