Joker

 In the following example, a default value is provided for eveything under map:
 
+----------------------------------------------+
map: {
	*: "default"
	foo: "Foo"
	bar: "Bar"
}
+----------------------------------------------+

 Resolving "map.foo" returns "Foo", resolving "map.bla" returns "default".
 
 Another possible use for a joker is:
 
+----------------------------------------------+
names: ${maps.*.name}

maps: {
	map1: {
		name: "Map 1"
	}
	map2: {
		name: "Map 2"
	}
	map3: {
		no-name-here: true
	}
}
+----------------------------------------------+

 Resolving "names" returns a map with this content:
 
+----------------------------------------------+
map1: "Map 1"
map2: "Map 2"
+----------------------------------------------+
 
 It is also possible to have more than one joker in a reference:
 
+----------------------------------------------+
nestedNames: ${nested.*.*.name}
nestedValues: ${nested.*.*.value}

nested: {
	colors: {
		red: {
			name: Red
			value: "#ff0000"
		}
		green: {
			name: Green
			value: "#00ff00"
		}
	}
	hello: {
		world: {
			name: HelloWorld
			value: "Hello world!"
		}
	}
}
+----------------------------------------------+

 Resolving "nestedNames" returns a map with this content:
 
+----------------------------------------------+
colors: {
	red: "Red"
	green: "Green"
}
hello: {
	world: "HelloWorld"
}
+----------------------------------------------+

 Resolving "nestedValues" returns a map with this content:
 
+----------------------------------------------+
colors: {
	red: "#ff0000"
	green: "#00ff00"
}
hello: {
	world: "Hello world!"
}
+----------------------------------------------+
