/**
 * Identifiers with special meaning become keywords in certain syntactic contexts:
 * <p/>
 * In a for-each-in statement between the 'for' token and the '(' token:
 * each
 * In a function definition between the 'function' token and an identifier token:
 * get set
 * As the first word of a directive:
 * namespace include
 * In an attribute list or wherever an attribute list can be used:
 * dynamic final native override static
 * <p/>
 * It is a syntax error to use a syntactic keyword in a context where it is treated as a keyword:
 * <p/>
 * namespace = "hello"
 * namespace()
 * <p/>
 * In these cases, the grammar requires an identifier after the namespace keyword.
