It seems to me that is an oversight. The resolution would be rather simple, cf. <https://github.com/php/php-src/blob/php-7.0.0beta3/Zend/zend_language_parser.y#L366-L375>. However, while looking at the grammar, I've noticed that the entities inside the braces may start with a backslash, what I consider rather strange (particularly as there has to be a backslash immediately before the opening brace). -- Christoph M.
