Expected Behaviour

[TomasVotruba]

Thank you for your report and demo link!

Could you send a failing test case in a pull-request, so we have it covered in Rector?
Here is step by step tutorial how to add it: https://github.com/rectorphp/rector/blob/master/docs/how_to_add_test_for_rector_rule.md

[stephanvierkant]

Any idea where I should add it? Since I got a fatal error, I don't know which rule is relevant.

[samsonasik]

You can run rector locally with --debug option to see what nearest rules that cause the error.

I failed to reproduce this issue in the rector-src repo. Can someone help me reproducing this issue? Thanks!
