Hacklib fatal error on PHP 7.1: 'Iterable' is a reserved word

[doublecompile]

The PHP code that h2tp outputs cannot be used on PHP 7.1 because iterable is now a reserved word.

This is done on an Ubuntu 16.04 machine that has:

• HHVM 3.17.2 (using the dl.hhvm.com/OSL deb repo)
• PHP 7.1 (using the PPA from Ondřej Surý)

$ php7.1 -a
Interactive mode enabled

php > require_once '/usr/share/hhvm/hack/hacklib/hacklib.php';
PHP Fatal error:  Cannot use 'Iterable' as class name as it is reserved in /usr/share/hhvm/hack/hacklib/containers/interfaces.php on line 97
PHP Stack trace:
PHP   1. {main}() php shell code:0
PHP   2. {main}() php shell code:0

[doublecompile]

As a side note, the PHP 7.1 iterable type hint now essentially duplicates what HH\Traversable does.

h2tp was removed from the repo. This is something you can work on by forking h2tp and making modifications there.

Others in the community are interested in creating a similar transpiler using the new full fidelity parser. You can read more about what they are thinking here.
