I would like to get something like: 

{"collection":"tags","example":{"name":"dima"}}

I am doing: 

	Json x = Json.emptyObject;
	x.collection = "tags";
	x.example = `{"name":"dima"}`;
	writeln(x.toString);

I am getting: 

{"collection":"tags","example":"{\"name\":\"dima\"}"}

What I am doing wrong? How to prevent slashes appearing?

Yes, you're assigning a string to a Json object's member.
You need to create a new object first, and then assign members to it. 

auto x = Json.emptyObject;
x.collection = "tags";
x.example = Json.emptyObject;
x.example.name = "dima";
writeln(x.toString);

Also, I believe the x.prop syntax is going to be deprecated, so you should instead use: 

auto x = Json.emptyObject;
x["collection"] = "tags";

auto example = Json.emptyObject;
example["name"] = "dima";

x["example"] = example;
