Bug #77539 [NEW]: BC break in heredoc syntax in 7.3

From: rasc at jfmedier dot dk Operating system: Windows 10 / WSL PHP version: 7.3.1 Package: PHP Language Specification Bug Type: Bug Bug description:BC break in heredoc syntax in 7.3 Description: ------------ PHP 7.3 introduced a minor BC syntax break against 7.2. Likely this regression was introduced while refactoring to introduce support for flexible heredoc/nowdoc syntax in 7.3. You can see a failing build here: https://travis-ci.org/kodus/mail/jobs/485801377 This build succeeds under 7.1 and 7.2, but fails under 7.3. You can see the parse error affecting 7.3.0 and 7.3.1 here: https://3v4l.org/1H0l7 (by the way: looks like the documentation page was never updated to reflect changed from the flexible heredoc/nowdoc syntax RFC.)
