Assert::keyExists() implemented failing unit test

[clxmstaab]

adds failing test for #39

it seems there is already some kind of keyExists handling, but it does not work yet for the added testcase

This issue is probably totally different, it's about ConstantArrayType::accepts() behaviour in core PHPStan.

hmm I guess this means I am lost now. Could you give me some more pointers? or is it something very deep in the core, which a beginner will not be able to fix?

I already tried to narrow it down on phpstan.org

using array_key_exists directly seem to work like expected.
https://phpstan.org/r/1d951760-7d0d-47bc-bed6-429eeaa5de58

I got the impression that phpstan rewrites the ast to something like

array_key_exists('password', $data);
array_key_exists('email', $data);
a($data);

while it should be more something like

if (array_key_exists('password', $data) && array_key_exists('email', $data)) {
	a($data);
}

If this works https://phpstan.org/r/47c28281-644a-4193-bb02-5fa61cbcb93f then this extension has to work too...

Hmm this looks like expected to me, right?

any more pointers where the error might come from?

[clxmstaab]

I dont know where the difference is, but I am now able to reproduce the issue on phpstan
