question: public static List < Node > parseExpression ( Context context , HashSet < String > configNamespaces , String text ) { return parseExpression ( context , configNamespaces , text , 0 , false ) ; }
target:  This method should be used to parse an expression, like "a = b".  It differs from the parse() methods in it's handling of expressions like "[a, b]", which are parsed as array literals, instead of metadata.
