+	/** 
+	 * The following is the exact list of additions to JSON's syntax introduced by JSON5. All of these are optional, and all of these come from ES5.
+
+Objects
+
+Object keys can be unquoted if they're valid identifiers. Yes, even reserved keywords (like default) are valid unquoted keys in ES5 [§11.1.5, §7.6]. (More info)
+
+(TODO: Unicode characters and escape sequences aren’t yet supported in this implementation.)
+
+Objects can have trailing commas.
+
+Arrays
+
+Arrays can have trailing commas.
+Strings
+
+Strings can be single-quoted.
+
+Strings can be split across multiple lines; just prefix each newline with a backslash. [ES5 §7.8.4]
+
+Numbers
+
+Numbers can be hexadecimal (base 16).
+
+Numbers can begin or end with a (leading or trailing) decimal point.
+
+Numbers can include Infinity, -Infinity, NaN, and -NaN.
+
+Numbers can begin with an explicit plus sign.
+
+Comments
+
+Both inline (single-line) and block (multi-line) comments are allowed.
