I'd like to request support for lambda syntax anonymous functions used by [Metalua ](https://github.com/fab13n/metalua)and [MoonSharp](https://github.com/moonsharp-devs/moonsharp). With lambda syntax ```lua |x, y| x + y ``` is treated as syntax sugar for: ```lua function(x, y) return x + y end ```
