Description:
------------
$count = $GLOBALS['cl_api']->$module['api_name']->count(0);
$count = $GLOBALS['cl_api']->{$module['api_name']}->count(0);

why in the world is the first a "array to string conversion" with PHP7
$module['api_name'] is clearly a field of a array and a string

while i suck all the changes in context of $$ that above is somehow unacceptable because there is hardly some clean way to seek for such things since seek for ]-> would also find any of similar but fine code and seek for ]->$ the same

AND AT LEAST there should have been done something in 5.6 to WARN about such needed changes without beraking applications at that point

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

You'd think a change like that would be documented, right?

I suspect it's not even possible to do this, but I'd rather not spend my time arguing with you.

We're not going to introduce posthumous deprecations on a *stable* branch.

congratulations, so deploy PHP7 will be some sort of "go ahead and look what breaks" since testing every line of code and action on staging systems is just utopic
 [2016-07-31 11:04 UTC] nikic@php.net 
From your comments I deduce that you do not have an automated test suite that would alleviate this problem. In that case, may I suggest the use of one of the many PHP 7 compatibility checkers out there? From a quick look, https://github.com/sstalle/php7cc has code that accurately detects syntax affected by UVS changes.
