Pattern: Use of namespaced assert()

Issue: -

Description

Detects declaration of a namespaced function called assert().

As of PHP 7.3, a compile-time deprecation warning will be thrown when a function called assert() is declared. In PHP 8 this will become a compile-error.

Methods are unaffected. Global, non-namespaced, assert() function declarations were always a fatal "function already declared" error, so not the concern of this sniff.

PHP version 7.3
