| Q | A | ---------------- | ----- | Bug report? | no | Feature request? | yes | BC Break report? | no | RFC? | no | Symfony version | 3.3.10 ExpressionValidator should use OBJECT_TO_STRING for formatValue, so i can use `{{ value }}` inside the message and it isn't replaced with just `'object'` i don't think it's more like a feature request then a pure bug, so i didn't make a (simple) pull request jet, but wait what you guys think about it.
