 Representation of Numbers

 integer and floating-point values by always serializing a floating-point number with a decimal point

+Parse JSON with Sub-Objects
+--------------------------
+
+`Engine::parse_json` depends on the fact that the [object map] literal syntax in Rhai is _almost_
+the same as a JSON object.  However, it is _almost_ because the syntax for a sub-object in JSON
+(i.e. "`{ ... }`") is different from a Rhai [object map] literal (i.e. "`#{ ... }`").
+
+When `Engine::parse_json` encounters JSON with sub-objects, it fails with a syntax error.
+
+If it is certain that no text string in the JSON will ever contain the character '`{`',
+then it is possible to parse it by first replacing all occupance of '`{`' with "`#{`".
+
+```rust
+// JSON with sub-object 'b'.
+let json = r#"{"a":1, "b":{"x":true, "y":false}}"#;
+
+let new_json = json.replace("{" "#{");
+
+// The leading '{' will also be replaced to '#{', but parse_json can handle this.
+let map = engine.parse_json(&new_json, false)?;
+
+map.len() == 2;       // 'map' contains two properties: 'a' and 'b'
