Hi Marco!
Trivial question - let's see what happens:
Just replace COPA with the old syntax and run it:
try {
$foo->a = 'a';
$foo->b = iThrow();
$foo->x = 'c';
} catch (\Throwable $e) {
var_export($foo); // ???
}
Result:
Foo::__set_state(array(
'a' => 'a',
'b' => NULL,
'c' => NULL,
))
So the first property will be set, the rest will be left as they were.
Best,
Jakob
