I found these snippets:
https://psalm.dev/r/6b7253ee73
<?php
class A {
public ?C $value;
}
class B extends A {
}
class C {
/** @psalm-var mixed */
public $value = [];
public function yay(): string
{
return 'yay';
}
}
function t(A $v): void
{
/** @psalm-trace $v->value */
if ($v->value) {
/** @psalm-trace $v->value */
if ($v instanceof B && 'yay' === $v->value->yay()) {
echo 'yay';
}
}
}
Psalm output (using commit 16b24bd):
ERROR: PossiblyNullReference - 25:53 - Cannot call method yay on possibly null value
INFO: Trace - 25:9 - $v->value: C
