Some ''actual'' problems I've found with PHP 7, after using PHP for the better part of two decades:
==Interfaces and Traits==
* Parameters can be declared to be of a given {{l/sub|class|PHP}} or a given {{l/sub|interface|PHP}}, but not a given {{l/sub|trait|PHP}}.
* Traits cannot be declared to implement interfaces.
** Interfaces and traits really kind of go together -- neither one is tied to a specific class; a trait can be thought of as a way of implementing a given interface -- but there is no way to attach one to the other. So even if you're systematically defining traits as implementations of specific interfaces, every class that uses the trait needs to also declare that it implements the interface.
* There is no way to dynamically test an object or class-name to see if it uses a trait or implements an interface.
