One-line heredoc for better syntax highlightning

Hi internals! Some editors can guess the domain-specific language inside heredoc, e.g. if you do $query = <<<MySQL SELECT * FROM foo MySQL; It would be nice if this feature could be used in single lines as well: $query = <<<MySQL SELECT * FROM foo MySQL; Any limitations in the parser that prevents this? Or just a convention or historical choice?
