> It would be a nice addition to the language if thrift supported a {{void}} field type for unions, this would be used for fields that are set but without a value, i.e. the act of setting it is all the information that is required. Take this example:
> {code}
> union Query {
>   // Find only this item
>   1: string only;
>   // Find any of these items
>   2: list<string> anyOf;
>   // Find all of these items
>   3: list<string> allOf;
>   // Every item
>   4: void all;
> }
> {code}
