Description:
------------
Following docs (http://php.net/manual/pt_BR/functions.arguments.php#functions.arguments.type-declaration.strict) when we have no declaration of strict_types or it's set to 0 the default behavior for scalar types is to coerce to declared type.

It's ok for string and boolean. When we set a parameter to int or float PHP throws a TypeError - the expected behavior for strict_types = 1.

When strict_types is set to 1 everything runs as expected.

Test script:
---------------
declare(strict_types = 0);
function test(int $grade)
{
    return $grade >= 7 ? 'X' : 'Y';
}

willInternTurnEmployee(8); //'Pass' and OK

echo willInternTurnEmployee('Really?');
//Expected: 'Fail', string converted to int
//TypeError thrown


Expected result:
----------------
Y

Actual result:
--------------
