PHP 7.0 Fatal Error

After upgrading to PHP7, WordPress Contact Forms by Cimatti stopped working. Here’s the error:

Fatal error: Uncaught Error: Function name must be a string in /path/to/plugin/wp-content/plugins/contact-forms/PFBC/Base.php:28

Line 28 was:
$this->$method_reference[“set” . $property]($value);

It needs to be:
$this->{$method_reference[“set” . $property]}($value);

There are other notices from Base.php:
Notice: Array to string conversion on lines 28 and 30

Notice: Undefined property: AccuaForm_Error_Standard::$Array on line 28

Any plans to support PHP7?
