 ===== Proposal ===== ===== Proposal =====
-This proposal adds a new syntax to add type hints to array destructuring expressions. The type hints behave identically to the type hints processed for function calls (compare https://wiki.php.net/rfc/scalar_type_hints_v5). This includes a controllability of the behaviour using the strict_types directive:+This proposal adds a new syntax to add type hints to array destructuring expressions. The type hints behave identically to the type hints processed for function calls (compare https://wiki.php.net/rfc/scalar_type_hints_v5). This includes a controllability of the behaviour using the strict_types directive. Type checks will be executed during the assignment of the variables when resolving the array destructuring expression. The variables will **not** keep any information concerning the check (they will not behave like typed variables afterwards, just like type checks in method signatures).
