Bug #72981 [Opn]: Interpolated strings cannot be dereferenced directly

Edit report at https://bugs.php.net/bug.php?id=72981&edit=1 ID: 72981 Updated by: cmb@php.net Reported by: nikic@php.net Summary: Interpolated strings cannot be dereferenced directly Status: Open Type: Bug Package: Scripting Engine problem PHP Version: master-Git-2016-08-30 (Git) Block user comment: N Private report: N New Comment: > As of PHP 5.6 it is possible to write "foo"[0].

Not sure, if we should try to fix this, since this feature appears to be rarely useful, and since it is possible to dereference arbitrary parenthesized expressions (as of PHP 7.0.0) which appears to be more readable for complex cases at least. With regard to Heredoc and Nowdoc direct dereferentiation seems to be even more doubtful, even if the Flexible Heredoc and Nowdoc Syntaxes RFC[1] will be implemented. I suggest to mark this as documentation issue.
